“I don’t hold out ecstatic hopes,” Alleyn said, “but get on with it.”

One of the plumbers pulled the chain and contemplated the ensuing phenomena.

“Well?” said Fox.

“I wouldn’t say she was a sweetly running job,” the plumber diagnosed, “and yet again she works if you can understand me.” He raised a finger, and glanced at his mate.

“Trap trouble?” ventured his mate.

“Ar.”

“We’ll leave you to it,” Alleyn said and withdrew Fox into the office. “Fox,” he said, “let’s remind ourselves of the key pieces in this jig-saw atrocity. What are they?”

Fox said promptly: “The set-up at Duke’s Gate. The drug racket. Harmony. The substitution. The piano-accordion. The nature of the the weapon.”

“Add one more. The metronome was motionless when Rivera played. It started its blasted tick-tack stuff after he fell and after the other rounds had been fired.”

“I get you, sir. Yes,” said Fox, placidly, “there’s that too. Add the metronome.”

“Now, let’s mug over the rest of the material and see where we are.”

Sitting in Caesar Bonn’s stale office, they sorted, discarded, correlated and dissociated the fragments of the case. Their voices droned on to the intermittent accompaniment of plumbers’ aquatics. After twenty minutes Fox shut his notebook, removed his spectacles and looked steadily at his superior officer.

“It amounts to this,” he said. “Setting aside a handful of insignificant details, we’re short of only one piece.” He poised his hand, palm down, over the table. “If we can lay hold of that and if, when we’ve got it, it fits — well, our little picture’s complete.”

“If,” Alleyn said, “and when.”

The door of the inner office opened and the senior plumber entered. With an air of false modesty he extended a naked arm and bleached hand. On the palm of the hand dripped a revolver. “Would this,” he asked glumly, “be what you was wanting?”

Dr. Curtis waited for them outside the main entrance to Breezy’s flat.

“Sorry to drag you out, Curtis,” Alleyn said, “but we may need your opinion about his fitness to make a statement. This is Fox’s party. He’s the drug baron.”

“How do you expect he’ll be, Doctor?” Fox asked.

Dr. Curtis stared at his shoes and said guardedly: “Heavy hangover. Shaky. Depressed. May be resentful. May be placatory. Can’t tell.”

“Suppose he decides to talk, is it likely to be truthful?”

“Not very. They usually lie.”

Fox said: “What’s the line to take? Tough or coaxing?”

“Use your own judgement.”

“You might tip us the wink, though, Doctor.”

“Well,” said Curtis, “let’s take a look at him.”

The flats were of the more dubious modern kind, and brandished chromium steel almost in the Breezy Bellairs Manner — showily and without significance. Alleyn, Fox and Curtis approached the flat by way of a rococo lift and a tunnel-like passage. Fox pressed a bell and a plain-clothes officer answered the door. When he saw them he snibbed back the lock and closed the door behind him.

“How is he?” Alleyn asked.

“Awake, sir. Quiet enough, but restless.”

“Said anything?” Fox asked. “To make sense, I mean.”

“Nothing much, Mr. Fox. Very worried about the deceased, he seems to be. Says he doesn’t know what he’s going to do without him.”

“That makes sense at all events,” Fox grunted. “Shall we go in, sir?”

It was an expensive and rather characterless flat, only remarkable for its high content of framed and signed photographs and its considerable disorder. Breezy, wearing a dressing gown of unbelievable sumptuousness, sat in a deep chair into which he seemed to shrink a little further, as they came in. His face was the colour of an uncooked fowl and as flabby. As soon as he saw Dr. Curtis he raised a lamentable wail.

“Doc,” he whined, “I’m all shot to heaps. Doc, for petesake take a look at me and tell them.”

Curtis picked up his wrist.

“Listen,” Breezy implored him, “you know a sick man when you see one — listen — ”

“Don’t talk.”

Breezy pulled at his lower lip, blinked at Alleyn and with the inconsequence of a ventriloquist’s doll flashed his celebrated smile.

“Excuse us,” he said.

Curtis tested his reflexes, turned up his eyelid and looked at his tongue.

“You’re a bit of a mess,” he said, “but there’s no reason why you shouldn’t answer any questions these gentlemen like to put to you.” He glanced at Fox. “He’s quite able to take in the usual warning,” he said.

Fox administered it and drew up a chair, facing Breezy, who shot out a quavering finger at Alleyn.

“What’s the idea,” he said, “shooing this chap on to me? What’s wrong with talking to me yourself?”

“Inspector Fox,” Alleyn said, “is concerned with investigations about the illicit drug trade. He wants some information from you.”

He turned away and Fox went into action.

“Well, now, Mr. Bellairs,” Fox said, “I think it’s only fair to tell you what we’ve ascertained so far. Save quite a bit of time, won’t it?”

“I can’t tell you a thing. I don’t know a thing.”

“We’re aware that you’re in the unfortunate position,” Fox said, “of having formed the taste for one of these drugs. Gets a real hold on you, doesn’t it, that sort of thing?”

Breezy said: “It’s only because I’m overworked. Give me a break and I’ll cut it out. I swear I will. But gradually. You have to make it gradual. That’s right, isn’t it, Doc?”

“I believe,” Fox said comfortably, “that’s the case. That’s what I understand. Now, about the supply. We’ve learnt on good authority that the deceased, in this instance, was the source of supply. Would you care to add anything to that statement, Mr. Bellairs?”

“Was it the old bee told you?” Breezy demanded. “I bet it was the old bee. Or Syd. Syd knew. Syd’s had it in for me. Dirty bolshevikl Was it Syd Skelton?”

Fox said that the information had come from more than one source and asked how Lord Pastern knew Rivera had provided the drugs.

Breezy replied that Lord Pastern nosed out all sorts of things. He refused to be drawn further.

“I understand,” Fox went on, “that his lordship tackled you in the matter last evening.”

Breezy at once became hysterical. “He’d ruin me! That’s what he’d do. Look! Whatever happens don’t let him do it. He’s crazy enough to do it. Honest. Honest he is.”

“Do what?”

“Like what he said. Write to that bloody paper about me.”

“Harmony?” Fox asked, at a venture. “Would that be the paper?”

“That’s right. He said he knew someone — God, he’s got a thing about it. You know — the stuff. Damn and blast him,” Breezy screamed out, “he’ll kill me. He killed Carlos and now what’ll I do, where’ll I get it? Everybody watching and spying and I don’t know. Carlos never told me. I don’t know.”

“Never told you?” Fox said peacefully. “Fancy that now! Never let on how he got it! And I bet he made it pretty hot when it came to paying up. Um?”

“God, you’re telling me!”

“And no reduction made, for instance, if you helped him out?”

Breezy shrank back in his chair. “I don’t know anything about that. I don’t get you at all.”

“Well, I mean to say,” Fox explained, “there’d be opportunities, wouldn’t there? Ladies, or it might be their partners, asking the band leader for a special number. A note changes hands and it might be a tip or it might be payment in advance, and the goods delivered next time. We’ve come across instances. I wondered if he got you to oblige him. You don’t have to say anything if you don’t want to, mind. We’ve the names and addresses of all the guests last night and we’ve got our records. People that are known to like it, you know. So I won’t press it. Don’t let it worry you. But I thought that he might have had some arrangement with you. Out of gratitude as you might put it — ”

“Gratitude!” Breezy laughed shrilly. “You think you know too much,” he said profoundly, and drew in his breath. He was short of breath and had broken into a sallow profuse sweat. “I don’t know what I’ll do without Carlos,” he whispered. “Someone’ll have to help me. It’s all the old bee’s fault. Him and the girl. If I could just have a smoke — ” He appealed to Dr. Curtis. “Not a prick. I know you won’t give me a prick. Just one little smoke. I don’t usually in the mornings but this is exceptional, Doc. Doc, couldn’t you — ”
