'Luncheon is served, my lady,' he announced.

Chapter 23.

ENCOUNTER IN THE ROSE GARDEN.

At 2.30 a little party met together in the council chamber: Bundle, Virginia, Superintendent Battle, M. Lemoine and Anthony Cade.

'No good waiting until we can get hold of Mr Lomax,' said Battle. 'This is the kind of business one wants to get on with quickly.'

'If you've got any idea that Prince Michael was murdered by someone who got in this way, you're wrong,' said Bundle. 'It can't be done. The other end's blocked completely.'

'There is no question of that, milady,' said Lemoine quickly. 'It is quite a different search that we make.'

'Looking for something, are you?' asked Bundle quickly. 'Not for the historic what-not, by any chance?'

Lemoine looked puzzled.

'Explain yourself, Bundle,' said Virginia encouragingly. 'You can when you try.'

'The thingummybob,' said Bundle. 'The historic diamond of purple princes that was pinched in the dark ages before I grew to years of discretion.'

'Who told you this, Lady Eileen?' asked Battle.

'I've always known. One of the footmen told me when I was twelve years old.'

'A footman,' said Battle. 'Lord! I'd like Mr Lomax to have heard that!'

'Is it one of George's closely guarded secrets?' asked Bundle. 'How perfectly screaming! I never really thought it was true. George always was an a.s.s - he must know that servants know everything.'

She went across to the Holbein portrait, touched a spring concealed somewhere at the side of it, and immediately, with a creaking noise, a section of the panelling swung inwards, revealing a dark opening.

'Entrez, messieurs et mesdames,' said Bundle dramatically. 'Walk up, walk up, walk up, dearies. Best show of the season, and only a tenner.'

Both Lemoine and Battle were provided with torches. They entered the dark aperture first, the others close on their heels.

'Air's nice and fresh,' remarked Battle. 'Must be ventilated somehow.'

He walked on ahead. The floor was rough uneven stone, but the walls were bricked. As Bundle had said, the pa.s.sage extended for a bare hundred yards. Then it came to an abrupt end with a fallen heap of masonry. Battle satisfied himself that there was no way of egress beyond, and then spoke over his shoulder.

'We'll go back, if you please. I wanted just to spy out the land, so to speak.'

In a few minutes they were back again at the panelled entrance.

'We'll start from here,' said Battle. 'Seven straight, eight left, three right. Take the first as paces.'

He paced seven steps carefully, and bending down examined the ground.

'About right, I should fancy. At one time or another, there's been a chalk mark made here. Now then, eight left. That's not paces, the pa.s.sage is only wide enough to go Indian file, anyway.'

'Say it in bricks,' suggested Anthony.

'Quite right, Mr Cade. Eight bricks from the bottom or the top on the left-hand side. Try from the bottom first - it's easier.'

He counted up eight bricks.

'Now three to the right of that. One, two, three - Hullo - Hullo, what's this?'

'I shall scream in a minute,' said Bundle, 'I know I shall What is it?'

Superintendent Battle was working at the brick with the point of his knife. His practised eye had quickly seen that this particular brick was different from the rest. A minute or two's work, and he was able to pull it right out. Behind was a small dark cavity. Battle thrust in his hand.

Everyone waited in breathless expectancy.

Battle drew out his hand again.

He uttered an exclamation of surprise and anger.

The others crowded round and stared uncomprehendingly at the three articles he held. For a moment it seemed as though their eyes must have deceived them.

A card of small pearl b.u.t.tons, a square of coa.r.s.e knitting, and a piece of paper on which were inscribed a row of capital E's!

'Well,' said Battle. 'I'm - I'm danged. What's the meaning of this?'

'Mon Dieu,' muttered the Frenchman. 'This is a little too much.'

'But what does it mean?' cried Virginia, bewildered.

'Mean?' said Anthony. 'There's only one thing it can mean. The late Count Stylpt.i.tch must have had a sense of humour! This is an example of that humor. I may say that I don't consider it particularly funny myself.'

'Do you mind explaining your meaning a little more clearly, sir?' said the Superintendent Battle.

'Certainly. This was the Count's little joke. He must have suspected that his memorandum had been read. When the crooks came to recover the jewel, they were to find instead this extremely clever conundrum. It's the sort of thing you pin on to yourself at Book Teas, when people have to guess what you are.'

'It has a meaning, then?'

'I should say, undoubtedly. If the Count had meant to be merely offensive, he would have put a placard with "Sold" on it, or a picture of a donkey or something crude like that.'

'A bit of knitting, some capital E's, and a lot of b.u.t.tons,' muttered Battle discontentedly.

'It is unheard of,' said Lemoine angrily.

'Cipher No 2,' said Anthony. 'I wonder whether Professor Wynwood would be any good at this one?'

'When was this pa.s.sage last used, milady?' asked the Frenchman of Bundle.

Bundle reflected.

'I don't believe anyone's been into it for over two years. The priest's hole is the show exhibit for Americans and tourists generally.'

'Curious,' murmured the Frenchman.

'Why curious?'

Lemoine stooped and picked up a small object from the floor.

'Because of this,' he said. 'This match has not lain here for two years - not even two days.'

Battle looked at the match curiously. It was of pink wood, with a yellow head. 'Any of you ladies or gentlemen drop this, by any chance?' he asked.

He received a negative all round.

'Well, then,' said Superintendent Battle, 'we've seen all there is to see. We might as well get out of here.'

The proposal was a.s.sented to by all. The panel had swung to, but Bundle showed them how it was fastened from the inside. She unlatched it, swung it noiselessly open, and sprang through the opening, alighting in the council chamber with a resounding thud.

'd.a.m.n!' said Lord Caterham, springing up from an armchair in which he appeared to have been taking forty winks.

'Poor old Father,' said Bundle. 'Did I startle you?'

'I can't think,' said Lord Caterham, 'why n.o.body nowadays ever sits still after a meal. It's a lost art. G.o.d knows Chimneys is big enough but even here there doesn't seem to be a single room where I can be sure of a little peace. Good Lord, how many of you are there? Reminds me of the pantomimes I used to go to as a boy when hordes of demons used to pop up out of trap doors.'

'Demon No 7,' said Virginia, approaching him, and patting him on the head. 'Don't be cross. We're just exploring secret pa.s.sages, that's all.'

'There seems to be a positive boom in secret pa.s.sages today,' grumbled Lord Caterham, not yet completely mollified. 'I've had to show that fellow Fish round them all this morning.'

'When was that?' asked Battle quickly.

'Just before lunch. It seems he'd heard of the one in here. I showed him that, and then took him up to the White Gallery, and we finished up with the priest's hole. But his enthusiasm was waning by that time. He looked bored to death. But I made him go through with it.' Lord Caterham chuckled at the remembrance.

Anthony put a hand on Lemoine's arm.

'Come outside,' he said softly. 'I want to speak to you.'

The two men went out together through the window. When they had gone a sufficient distance from the house, Anthony drew from his pocket the sc.r.a.p of paper that Boris had given him that morning.

'Look here,' he said. 'Did you drop this?'

Lemoine took it and examined it with some interest.

'No,' he said. 'I have never seen it before. Why?'

'Quite sure?'

'Absolutely sure, monsieur.'

'That's very odd.'

He repeated to Lemoine what Boris had said. The other listened with close attention.

'No, I did not drop it. You say he found it in that clump of trees?'

'Well, I a.s.sumed so, but he did not actually say so.'

'It is just possible that it might have fluttered out of M. Isaacstein's suitcase. Question Boris again.' He handed the paper back to Anthony. After a minute or two he said: 'What exactly do you know of this man Boris?'

Anthony shrugged his shoulders.

'I understood he was the late Prince Michael's trusted servant.'

'It may be so, but make it your business to find out. Ask someone who knows, such as the Baron Lolopretjzyl. Perhaps this man was engaged but a few weeks ago. For myself, I have believed him honest. But who knows? King Victor is quite capable of making himself into a trusted servant at a moment's notice.'

'Do you really think -'

Lemoine interrupted him.

'I will be quite frank. With me, King Victor is an obsession. I see him everywhere. At this moment even I ask myself - this man who is talking to me, M. Cade, is he, perhaps, King Victor?'

'Good Lord,' said Anthony, 'you have got it badly.'

'What do I care for the diamond? For the discovery of the murderer of Prince Michael? I leave those affairs to my colleague of Scotland Yard whose business it is. Me, I run in England for one purpose, and one purpose only, to capture King Victor and capture him red-handed. Nothing else matters.'

'Think you'll do it?' asked Anthony, lighting a cigarette.

'How should I know?' said Lemoine, with sudden despondency.

'Hm!' said Anthony.

They had regained the terrace. Superintendent Battle was standing near the french window in a wooden att.i.tude.

'Look at poor old Battle,' said Anthony. 'Let's go and cheer him up.' He paused a minute, and said, 'You know, you're an odd fish in some ways, M. Lemoine.'

'In what ways, M. Cade?'

'Well,' said Anthony, 'in your place, I should have been inclined to note down that address that I showed you. It may be of no importance - quite conceivably. On the other hand, it might be very important indeed.'

Lemoine looked at him for a minute or two steadily. Then, with a slight smile, he drew back the cuff of his left coat-sleeve. Pencilled on the white shirt-cuff beneath were the words 'Hurstmere, Langly Road, Dover'.

'I apologize,' said Anthony. 'And I retire worsted.'

He joined Superintendent Battle.

'You look very pensive, Battle,' he remarked.
