'I have indeed. You see, I've been spending the day down here with '

He turned to Evadne.

' with the well-known mystery writer Evadne Mount.'

'Ah yes, of course,' said Calvert warmly, shaking her hand. 'Very pleased to re-make your acquaintance, Miss Mount. And just let me say how terribly sorry I am. I know that Cora Rutherford was a very old friend of yours.'

'Re-make her acquaintance?' said a baffled Trubshawe. 'What do you mean by that?'

'Have you forgotten, Eustace?' said the novelist, 'When I wanted to invite you down here, it was Mr Calvert who was kind enough to give me your home address.'

Before Trubshawe could reply, Calvert, who had to stifle a smile on hearing the Chief-Inspector's Christian name, explained: 'That's right, sir. I did give Miss Mount your address. I know we're not supposed to do that, even for retired officers like yourself, but she insisted you'd be glad to hear from her and I a.s.sumed ...'

'Not at all, not at all,' Trubshawe answered genially. 'As a matter of fact, I was extremely glad. Unfortunately, what started out so very pleasantly has now turned into a nightmare.'

'It's a nasty one all right.'

'She was poisoned, I suppose?'

'It's what all the signs point to, sir. Of course, the doctor's only just arrived, and even he won't be able to give us anything conclusive until he's performed an autopsy. Poison, though, would seem to be the obvious bet so far. Which poison is another matter.'

'No lingering aroma of burnt almonds, I suppose?' asked Evadne Mount.

'I wouldn't know,' said Calvert. 'But I'm afraid, Miss Mount, since we're in the real world here, we can't rely on having that kind of clue served up to us on a plate.'

He turned to address Trubshawe again.

'The police surgeon that's Dr Beckwith, by the way, you probably remember him from the old days '

Trubshawe nodded.

'Well, he's a cagey one, the type that won't say much till he's two hundred-percent sure of his facts and figures, but I did get it out of him that he thought it most likely to be one of the acid-based poisons. They're quite tasteless and colourless, you see, and, even if they're pretty horrendous things to swallow, it's all over in ten seconds. As I say, though, we won't really know until the autopsy.'

'A tricky case, Calvert,' said Trubshawe, 'with so many people milling around.'

'You can say that again,' replied Calvert with a sigh. 'Between the lunch break and the moment Cora Rutherford dropped dead, do you know that there were no fewer than forty-three people on the studio set? And all of them had an opportunity to administer the poison. We already know when the lemonade was poured into the gla.s.s, and by whom, but that's it.'

'Lemonade? I thought it was champagne.'

'Can't have the cast quaffing champagne, you know. No, it was some kind of transparent soda pop. As the doctor was examining the body, this chap came forward almost in tears, he was he'd been in charge of props and it was he who, at one o'clock, just as the afternoon filming was about to start, opened a bottle of the fizzy stuff and half-filled the champagne gla.s.s, as per his instructions. He wanted to get his defence in before he was questioned, and I can't say I blame him. The first person we would have gone after was whoever actually filled the gla.s.s.'

'And he's to be believed, you think?'

'Oh, I really can't imagine why not. No motive, you see. Been in the picture business upwards of thirty years, so he claims. And, above all, he's got witnesses.'

'Witnesses?'

'It appears that his a.s.sistant, the chap who brought the bottle of lemonade from the studio canteen, actually hung around long enough to see him unscrew the top.'

'I don't suppose the bottle could already have been tampered with in the canteen itself?'

'Not a chance. It was picked up at random out of a couple of dozen on display. And the top was unscrewed in the presence of this lady here' he indicated Lettice 'who also verified that the gla.s.s had just enough liquid in it.'

He hesitated, turning to Lettice herself to complete the explanation.

'Tell us again, Miss, what you just told me.'

Lettice answered with characteristic composure.

'The fact is,' she said to Trubshawe, 'I'm responsible for what's called continuity, for making sure that, if there's a red handkerchief in an actor's jacket pocket in one scene, it hasn't turned into a yellow handkerchief in the next, that kind of detail. Well, when Props his real name's Stan but everybody calls him Props when Props came on set with the bottle of lemonade, I had to be present to check that there was going to be exactly the right amount of "champagne" in Miss Rutherford's gla.s.s. And I can testify that Props opened the bottle in front of me.'

'So that puts him out.' Calvert sighed once more. 'Which leaves us with just forty-two potential suspects, any one of whom could have introduced the poison. I've already gathered these picture people are a pretty talkative lot, I can tell you I've already gathered that it takes so long to set up a new shot, as they say, that the gla.s.s sat on the table for about an hour while everyone went about their respective jobs, installing lights, laying cables, making up the actors and actresses and I don't know what else. I haven't a clue where we're going to start. In fact, I haven't a clue, full stop.'

'Then may I offer you one?' said Evadne Mount, who had been paying close attention to the exchanges between Calvert and Trubshawe.

'One what?'

'Clue. An important one, if I'm not in error.'

'I'd be grateful, Miss Mount, for even the most trivial of clues.'

'Well,' she said, 'as Eustace here will confirm, we watched this morning's filming together before going off to the commissary to lunch with Cora. And it was during our meal that she mentioned how Rex Hanway, the director, had taken her aside just before the break to tell her about a new idea he'd had for the afternoon's big scene, the idea being that there should be some champagne, or lemonade, still in the gla.s.s and that Cora should swallow it before throwing it at Gareth Knight. In the original script, you see, she was simply to pick up an empty gla.s.s, which was naturally how everyone expected it to be filmed.

'Ergo,' she ended, taking evident pleasure in hearing the Latin word trip off her tongue, 'whoever decided to poison Cora could only have hatched the plot between twelve noon, when Hanway apprised her of his idea, and two o'clock, when she herself drank the lemonade.'

'Curses!' Trubshawe berated himself. 'Why didn't I think of that?'

'Which means, of course,' she went on, once more raising her arm like a policeman to control the conversational traffic, and more especially to warn the Chief-Inspector not to venture down what she regarded as her own private one-way street, 'that the murderer would also have had to belong to what must surely be an extremely select group. That's to say, only those who were actually privy to Hanway's change of plan.'

Both Calvert and Trubshawe instantly saw the justice and relevance of her words.

'My G.o.d, Evie!' cried Trubshawe. 'Poor old Cora has just been murdered and already you've come up with an important clue. You're the real thing.'

'Yes, bravo!' Calvert chimed in. 'With that one insight you've considerably narrowed the scope of the investigation. Now all we have to do is draw up a list of everyone whose job would have necessitated their being told of the business with the champagne gla.s.s. My word, we're actually getting somewhere.'

'Is there any reason, Mr Calvert, why we don't start right away?' asked the novelist. 'This crime isn't going to solve itself.'

'What do you mean, start right away?'

'Start drawing up a list. It shouldn't take too long. I can't believe that any of the what did Cora call them? the ordinary grips and geezers would have been informed of the change. As I said, it could only have been a select few. Indeed, I rather think a couple of the prime suspects may be sitting right here in this room.'

Hearing these last words, Calvert, who had been nodding over each pertinent point raised in the conversation, stiffened almost as though he were immediately preparing to apprehend, with handcuffs if necessary, the two about-to-be-designated suspects.

For his part, however, Trubshawe merely smiled.

'If I'm not mistaken, Tom,' he said, 'she means us me and her. I'm right, Evie, aren't I?'

When the novelist nodded in agreement, Calvert shook his head.

'You two as suspects? Come now, Miss, let's be serious.'

'Oh, I a.s.sure you, I am being serious, deadly serious. What would be the point of drawing up such a list if it weren't both inclusive and unbiased? Eustace and I were the very first to hear, from Cora's own lips, of the new bit of business. And even though, this afternoon, not once were we out of each other's sight also, as mere visitors, practically interlopers, neither of us was permitted to approach the actual performing area we were nevertheless physically present at the scene of the murder and might well have committed it, singly or in tandem, via some incredibly deft sleight-of-hand. One of those impossible crimes you read about in the anthologies.'

'All right, Miss Mount,' said Calvert, 'we'll have it your way if you insist. You and Mr Trubshawe are Suspects 1 and 2. Now shall we get down to bra.s.s tacks? The third suspect and, as far as I'm concerned, the first in any real sense must be this Rex Hanway. The idea was his, after all.'

'Ah, but don't you see, Inspector, unless I'm very much mistaken, the fact that Hanway actually directed Cora to drink from a gla.s.s of lemonade which turned out to be poisoned is going to be precisely his alibi.'

'His alibi? Why, it's the very contrary of an alibi.'

'Not at all,' she replied. 'I can just hear how he might respond to any such accusation you level against him. "My dear Inspector,"' she went on in a remarkably lifelike imitation of the director's cut-gla.s.s vowels, "if I'd really planned to murder poor, darling Cora, do you suppose I'd have told her in public, mark you, in public to drink out of a gla.s.s I already knew to contain poison?"'

'H'm,' said Calvert, stroking his cheek, on which few traces were visible of a razor's coa.r.s.ening attentions. 'I see what you mean ...'

It was now Trubshawe's turn to speak.

'Hold on a sec there,' he said. 'Yes, Evie has cleverly shown why we need take far fewer than the original forty-two suspects into serious consideration. Hats off to her, even though,' he added a trifle ungraciously, 'it's a point that one or other of us would have made eventually. But there's something else she seems to have forgotten.'

'Oh,' said Evadne, 'and what's that, may I ask?'

'Well, of course I don't claim to know much about film folk, but I have had a lot of experience of murderers. Now someone who had a premeditated intent to kill might well decide to visit the scene of his intended crime with a pistol or a revolver or even a knife concealed about his person in the hope that a suitable moment would arise for committing it. But poison? Until just before the lunch break there was no question of Cora drinking out of the champagne gla.s.s. Do either of you seriously believe that her murderer has been strolling around the set these past few days ever since they started making this cursed film with a flask of poison tucked inside his or her pocket? Eh? And, if not, where would they be expected to lay hands on such a flask in the two hours or so that elapsed between Hanway coming up with his new idea and Cora swallowing the poison? Answer me that.'

Calvert's eyebrows registered the logic of the Chief-Inspector's argument.

'Ye-es, that's certainly another point we ought to consider.'

'I should think it is,' said Trubshawe. 'And what it means is that Hanway surely remains your number-one suspect.'

'All right,' said Calvert, 'that makes three we know of, you two and Hanway. Anyone else come to mind?'

'Philippe Francaix,' suggested Evadne Mount.

'Who's he when he's at home?'

'A French film critic.'

'Nuff said. I don't have much time for critics myself. All they ever do is criticise.'

'He's one of Farjeon's greatest admirers writing a book about him, or so he claims and he's here in Elstree to follow the shooting of the picture. He also, pretty much at his own invitation, I should tell you, lunched with Eustace, Cora and me in the commissary. So he knew all about the champagne gla.s.s.'

'Any conceivable motive?'

'Just like that, Tom?' said Trubshawe. 'We met the chap for the first time only two or three hours ago. Give us old lags a chance, will you.'

'What's your opinion, Miss Mount?'

'On this occasion I'd have to agree with Eustace. Except ... except that there was something ...'

'Something?'

'A feeling I had,' she replied, momentarily lost in thought. 'Not even a hunch. Nothing worth repeating. Not yet anyhow.'

'So. We have four suspects now. Who else?'

'Me.'

Everyone turned, startled, to face Lettice Morley.

'You, Miss? Are you admitting that you're a suspect?'

'I admit nothing,' she answered with the always slightly off-putting self-possession that seemed to be her defining trait. 'All I'm saying is that, if I accept the criteria by which you're in the process of designating suspects, then I cannot fairly exclude myself.'

'Sorry, but your name is ...?'

'Lettice Morley. I'm Rex's I should say, Mr Hanway's personal a.s.sistant. As such, I naturally have to know everything that occurs to him at the very instant it does occur to him. When he suggested to Miss Rutherford that she drink the champagne, he at once informed me too, and I went off and told Props, so that the half-filled gla.s.s would be precisely where it was supposed to be just as soon as Rex was ready to film the shot.'

'I see,' said Calvert. 'Well, thank you for being so candid. It's most unusual, most refreshing.'

'Not for a second, you understand,' she carried on imperturbably, 'am I intimating that I murdered Cora Rutherford. Even if the woman's irresponsible antics exasperated me, there was nothing personal in my dislike of her and, as my professional future is bound up in my making good on this picture, it would have been very foolish of me to jeopardise its own future by b.u.mping off one of the cast members.

'However,' she added, to her listeners' undiminished amazement, 'since you've already hit upon all kinds of clever clues, perhaps I might indicate one of my own before it's turned against me. I've read quite a few whodunits in my day yours among them, Miss Mount and, if there's one thing I've learned from them, it's that poison is traditionally a woman's weapon.'

She looked towards Evadne Mount for confirmation.

'Isn't that so?'

'We-ell ...' said the novelist, close to speechless for once, 'I suppose it is one of the conventions of the genre. But it doesn't mean we whodunit writers believe that, every time someone is poisoned, a woman necessarily did it.'

'No?' said Lettice. 'It's certainly the impression you leave the reader.'

'Ah but, Miss, if you have read Evie's novels,' said Trubshawe, 'you should remember that, in at least two of them, it turns out that a male murderer used poison precisely in order to lead the police astray hoping they'd suspect that the crime had been committed by a woman.'

'That may be so, I suppose. I merely mention what Miss Mount called the convention to remind you that, on the face of it, the fact that Miss Rutherford was poisoned would seem to make me an even likelier suspect than the others on your list.'

Her tirade had left them all shaking their heads, both in puzzlement and in open admiration. Calvert finally broke the silence.

'Very well. That would appear to make you Suspect No. 5. And since you've been so admirably frank in expressing your opinions, Miss, since you also know your way about the studio better than any of us, perhaps you yourself would propose a candidate for No. 6.'

'Certainly,' said Lettice with the same unruffled aplomb that she had displayed from the start. 'Not only No. 6 but No. 7. As someone is bound to point this out to you sooner or later, it may as well be me and it may as well be now. Gareth Knight and Leolia Drake will also have to be regarded as potential suspects.'

'Gareth Knight, eh?' said Calvert. 'Don't I know that name?'

'I should hope you do. He's the leading actor in If Ever They Find Me Dead and it was I who personally alerted him. He had to know of the alteration to the script because he was due to play the scene in question opposite Miss Rutherford. I told him just before he went off to lunch.'

'And Miss Drake?'

'She and Mr Knight happened to be chatting together at the time. Naturally, she too was made aware of the business with the champagne gla.s.s, even though it didn't affect any of her own scenes.'

'Well, thank you again, Miss Morley, you've been extremely helpful, more so, indeed, than I had any right to expect.'
