Ding, dong, dang, ding.

"For G.o.d's sake stop those bells," cried Mr. Hislop. Chase turned off the wall switch. Into the sudden silence came the sound of the doorhandle being rattled and Guy Tonks's voice on the other side.

"Hislop! Mr. Hislop! Chase! What's the matter?"

"Just a moment, Mr. Guy." Chase looked at the secretary. "You go, sir."

So it was left to Mr. Hislop to break the news to the family. They listened to his stammering revelation in stupefied silence. It was not until Guy, the eldest of the three children, stood in the study that any practical suggestion was made.

"What has killed him?" asked Guy.

"It's extraordinary," burbled Hislop. "Extraordinary. He looks as if he'd been--"

"Galvanised," said Guy.

"We ought to send for a doctor," suggested Hislop timidly.

"Of course. Will you, Mr. Hislop? Dr. Meadows."

Hislop went to the telephone and Guy returned to his family. Dr. Meadows lived on the other side of the square and arrived in five minutes. He examined the body without moving it. He questioned Chase and Hislop. Chase was very voluble about the burns on the hand. He uttered the word "electrocution" over and over again.

"I had a cousin, sir, that was struck by lightning. As soon as I saw the hand--"

"Yes, yes," said Dr. Meadows. "So you said. I can see the burns for myself."

"Electrocution," repeated Chase. "There'll have to be an inquest."

Dr. Meadows snapped at him, summoned Emily, and then saw the rest of the family-Guy, Arthur, Phillipa, and their mother. They were cl.u.s.tered round a cold grate in the drawing-room. Phillipa was on her knees, trying to light the fire.

"What was it?" asked Arthur as soon as the doctor came in.

"Looks like electric shock. Guy, I'll have a word with you if you please. Phillipa, look after your mother, there's a good child. Coffee with a dash of brandy. Where are those d.a.m.n maids? Come on, Guy."

Alone with Guy, he said they'd have to send for the police.

"The police!" Guy's dark face turned very pale. "Why? What's it got to do with them?"

"Nothing, as like as not, but they'll have to be notified. I can't give a certificate as things are. If it's electrocution, how did it happen?"

"But the police!" said Guy. "That's simply ghastly. Dr. Meadows, for G.o.d's sake couldn't you--?"

"No," said Dr. Meadows, "I couldn't. Sorry, Guy, but there it is."

"But can't we wait a moment? Look at him again. You haven't examined him properly."

"I don't want to move him, that's why. Pull yourself together, boy. Look here. I've got a pal in the CID-Alleyn. He's a gentleman and all that. He'll curse me like a fury, but he'll come if he's in London, and he'll make things easier for you. Go back to your mother. I'll ring Alleyn up."

That was how it came about that Chief Detective-Inspector Roderick Alleyn spent his Christmas Day in harness. As a matter of fact he was on duty, and as he pointed out to Dr. Meadows, would have had to turn out and visit his miserable Tonkses in any case. When he did arrive it was with his usual air of remote courtesy. He was accompanied by a tall, thick-set officer-Inspector Fox-and by the divisional police-surgeon. Dr. Meadows took them into the study. Alleyn, in his turn, looked at the horror that had been Septimus.

"Was he like this when he was found?"

"No. I understand he was leaning forward with his hands on the ledge of the cabinet. He must have slumped forward and been propped up by the chair arms and the cabinet."

"Who moved him?"

"Chase, the butler. He said he only meant to raise the arm. Rigor is well established."

Alleyn put his hand behind the rigid neck and pushed. The body fell forward into its original position.

"There you are, Curtis," said Alleyn to the divisional surgeon. He turned to Fox. "Get the camera man, will you, Fox?"

The photographer took four shots and departed. Alleyn marked the position of the hands and feet with chalk, made a careful plan of the room and turned to the doctors.

"Is it electrocution, do you think?"

"Looks like it," said Curtis. "Have to be a PM, of course."

"Of course. Still, look at the hands. Burns. Thumb and two fingers bunched together and exactly the distance between the two k.n.o.bs apart. He'd been tuning his hurdy-gurdy."

"By gum," said Inspector Fox, speaking for the first time.

"D'you mean he got a lethal shock from his radio?" asked Dr. Meadows.

"I don't know. I merely conclude he had his hands on the k.n.o.bs when he died."

"It was still going when the housemaid found him. Chase turned it off and got no shock."

"Yours, partner," said Alleyn, turning to Fox. Fox stooped down to the wall switch.

"Careful," said Alleyn.

"I've got rubber soles," said Fox, and switched it on. The radio hummed, gathered volume, and found itself.

"No-o-el, No-o-el," it roared. Fox cut it off and pulled out the wall plug.

"I'd like to have a look inside this set," he said.

"So you shall, old boy, so you shall," rejoined Alleyn. "Before you begin, I think we'd better move the body. Will you see to that, Meadows? Fox, get Bailey, will you? He's out in the car."

Curtis, Hislop, and Meadows carried Septimus Tonks into a spare downstairs room. It was a difficult and horrible business with that contorted body. Dr. Meadows came back alone, mopping his brow, to find Detective-Sergeant Bailey, a fingerprint expert, at work on the wireless cabinet.

"What's all this?" asked Dr. Meadows. "Do you want to find out if he'd been fooling round with the innards?"

"He," said Alleyn, "or-somebody else."

"Umph!" Dr. Meadows looked at the Inspector. "You agree with me, it seems. Do you suspect--?"

"Suspect? I'm the least suspicious man alive. I'm merely being tidy. Well, Bailey?"

"I've got a good one off the chair arm. That'll be the deceased's, won't it, sir?"

"No doubt. We'll check up later. What about the wireless?"

Fox, wearing a glove, pulled off the k.n.o.b of the volume control.

"Seems to be OK," said Bailey. "It's a sweet bit of work. Not too bad at all, sir." He turned his torch into the back of the radio, undid a couple of screws underneath the set, lifted out the works.

"What's the little hole for?" asked Alleyn.

"What's that, sir?" said Fox.

"There's a hole bored through the panel above the k.n.o.b. About an eighth of an inch in diameter. The rim of the k.n.o.b hides it. One might easily miss it. Move your torch, Bailey. Yes. There, do you see?"

Fox bent down and uttered a ba.s.s growl. A fine needle of light came through the front of the radio.

"That's peculiar, sir," said Bailey from the other side. "I don't get the idea at all."

Alleyn pulled out the tuning k.n.o.b.

"There's another one there," he murmured. "Yes. Nice clean little holes. Newly bored. Unusual, I take it?"

"Unusual's the word, sir," said Fox.

"Run away, Meadows," said Alleyn.

"Why the devil?" asked Dr. Meadows indignantly. "What are you driving at? Why shouldn't I be here?"

"You ought to be with the sorrowing relatives. Where's your corpseside manner?"

"I've settled them. What are you up to?"

"Who's being suspicious now?" asked Alleyn mildly. "You may stay for a moment. Tell me about the Tonkses. Who are they? What are they? What sort of a man was Septimus?"

"If you must know, he was a d.a.m.ned unpleasant sort of a man."

"Tell me about him."

Dr. Meadows sat down and lit a cigarette.

"He was a self-made bloke," he said, "as hard as nails and-well, coa.r.s.e rather than vulgar."

"Like Dr. Johnson perhaps?"

"Not in the least. Don't interrupt. I've known him for twenty-five years. His wife was a neighbour of ours in Dorset. Isabel Foreston. I brought the children into this vale of tears and, by jove, in many ways it's been one for them. It's an extraordinary household. For the last ten years Isabel's condition has been the sort that sends these psycho-jokers dizzy with rapture. I'm only an out-of-date GP, and I'd just say she is in an advanced stage of hysterical neurosis. Frightened into fits of her husband."

"I can't understand these holes," grumbled Fox to Bailey.

"Go on, Meadows," said Alleyn.

"I tackled Sep about her eighteen months ago. Told him the trouble was in her mind. He eyed me with a sort of grin on his face and said: 'I'm surprised to learn that my wife has enough mentality to--' But look here, Alleyn, I can't talk about my patients like this. What the devil am I thinking about."

"You know perfectly well it'll go no further unless--"

"Unless what?"

"Unless it has to. Do go on."

But Dr. Meadows hurriedly withdrew behind his professional rect.i.tude. All he would say was that Mr. Tonks had suffered from high blood pressure and a weak heart, that Guy was in his father's city office, that Arthur had wanted to study art and had been told to read for law, and that Phillipa wanted to go on to the stage and had been told to do nothing of the sort.

"Bullied his children," commented Alleyn.

"Find out for yourself. I'm off." Dr. Meadows got as far as the door and came back.

"Look here," he said, "I'll tell you one thing. There was a row here last night. I'd asked Hislop, who's a sensible little beggar, to let me know if anything happened to upset Mrs. Sep. Upset her badly, you know. To be indiscreet again, I said he'd better let me know if Sep cut up rough, because Isabel and the young had had about as much of that as they could stand. He was drinking pretty heavily. Hislop rang me up at ten-twenty last night to say there'd been a h.e.l.l of a row; Sep bullying Phips-Phillipa, you know; always call her Phips-in her room. He said Isabel-Mrs. Sep-had gone to bed. I'd had a big day and I didn't want to turn out. I told him to ring again in half an hour if things hadn't quieted down. I told him to keep out of Sep's way and stay in his own room, which is next to Phips's, and see if she was all right when Sep cleared out. Hislop was involved. I won't tell you how. The servants were all out. I said that if I didn't hear from him in half an hour I'd ring again and if there was no answer I'd know they were all in bed and quiet. I did ring, got no answer, and went to bed myself. That's all. I'm off. Curtis knows where to find me. You'll want me for the inquest, I suppose. Goodbye."

When he had gone Alleyn embarked on a systematic prowl round the room. Fox and Bailey were still deeply engrossed with the wireless.

"I don't see how the gentleman could have got a b.u.mp-off from the instrument," grumbled Fox. "These control k.n.o.bs are quite in order. Everything's as it should be. Look here, sir."

He turned on the wall switch and tuned in. There was a prolonged humming.

"... concludes the programme of Christmas carols," said the radio.

"A very nice tone," said Fox approvingly.

"Here's something, sir," announced Bailey suddenly.

"Found the sawdust, have you?" said Alleyn.

"Got it in one," said the startled Bailey.

Alleyn peered into the instrument, using the torch. He scooped up two tiny traces of sawdust from under the holes.

"Vantage number one," said Alleyn. He bent down to the wall plug. "Hullo! A two-way adapter. Serves the radio and the radiator. Thought they were illegal. This is a rum business. Let's have another look at those k.n.o.bs."

He had his look. They were the usual wireless fitments, Bakelite k.n.o.bs fitting snugly to the steel shafts that projected from the front panel.

"As you say," he murmured, "quite in order. Wait a bit." He produced a pocket lens and squinted at one of the shafts. "Ye-es. Do they ever wrap blotting-paper round these objects, Fox?"

"Blotting-paper!" e.j.a.c.u.l.a.t.ed Fox. "They do not."

Alleyn sc.r.a.ped at both the shafts with his penknife, holding an envelope underneath. He rose, groaning, and crossed to the desk. "A corner torn off the bottom bit of blotch," he said presently. "No prints on the wireless, I think you said, Bailey?" "That's right," agreed Bailey morosely.

"There'll be none, or too many, on the blotter, but try, Bailey, try," said Alleyn. He wandered about the room, his eyes on the floor; got as far as the window and stopped.

"Fox!" he said. "A clue. A very palpable clue."

"What is it?" asked Fox.
