From somewhere towards the back a doubtful voice uttered the word ‘flagellation’ and followed it with an apologetic little cough. Someone else made the noise ‘gatcha’ upon which there was a muffled guffaw.
“You’ll have to do better than that,” Alleyn said. “However: to press on with Mr Fox’s investigations. He found nothing else of interest at the Crossdyke end and moved to the stretch of river below Ramsdyke weir where the body was found. Above Ramsdyke near the hollow called Wapentake Pot, the road from Crossdyke and Tollardwark was undergoing repairs. There were loose stones and rubble. It crosses Dyke Way and Dyke Way leads down to a bridge over The River where the Roman canal joins it. Downstream from here is the weir with its own bridge, a narrow affair with a single handrail. It’s here that the effluent from a factory enters the mainstream and brews a great mass of detergent foam over the lower reaches.
“The weir bridge is narrow, green, wet and slithery with foam blown back from the fall. It is approached from the road by concrete steps and a cinder path.
“Along this path, Mr Fox again found a thread or two of dark blue synthetic caught on a bramble. Here’s the photograph. And I may tell you that a close search of the pyjamas revealed a triangular gap that matched the fragment from Crossdyke. Classic stuff.
“The path is bordered on one side by a very old wall from which a number of bricks had worked loose.
“Now for the weir bridge. Nearly three days had passed between the night she disappeared and our work on it. A pretty dense film of detergent had been blown back and it was a particularly awkward job to examine it without destroying any evidence there might be. However. There was a notice warning people that it was dangerous to use the bridge and the lock-keeper said he didn’t think anyone had been on it for at least a week.
“Mr. Fox found some evidence of recent gloved hand-holds on the rail. No prints were obtainable. For a distance of about twelve feet from the bank the actual footway looked to be less thickly encrusted than the remaining stretch of the bridge. Mr Fox reckoned that there was a sort of family resemblance between the appearance of the bridge and the drag over the heel prints on the bank at Crossdyke. Here are Thompson’s blow-ups for comparison. You can see how bad, from our point of view, the conditions were on the bridge.
“Now, out of all this, what sort of picture do you begin to get. Yes? All right, Carmichael?”
Carmichael rose, fixed Alleyn with his blue stare and delivered.
“To re-cap, sir,” Carmichael began ominously. “As a wur-r-r—king hypothesis, it could be argued that the bawdy of the deceased had been passed from the deck of the vessel into the possession of the persons who received it and that it had maybe been drawped and dragged in the process, sir, thus pairtially obleeterating the heel prints. Furthermore it could be reasonably deduced, sir, that the bawdy was transported by means of the motor-bike to Ramsdyke where it was conveyed by hand to the weir bridge, dragged some twelve feet along it and consigned to the watter.”
He stopped, cleared his throat and raised his hand: “As a rider to the above, sir, and proceeding out of it, “ he said. ”A suitcase, being the personal property of deceased, and packed with her effects, was removed from her cabin and transferred by the means already detailed, with the bawdy, to the said weir and there, weighted with stones and gravel and a half-brick, attached to the bawdy by the cord produced. The bawdy and the suitcase were then as detailed consigned to the watter.”
He resumed his seat and gave Alleyn a modest smile.
“Yes, Carmichael, yes,” Alleyn said, “and what about the post-mortem marks of the cord?”
Carmichael rose again.
“For want of an alternative,” he said with the utmost complacency, “I would assume as a wurrking premiss, sir, that the deed bawdy was lashed to the person of the cyclist thus rendering the spurious appearance of a pillion-rider.”
“Revolting as the picture you conjure up may be,” Alleyn said. “I’m afraid you’re right, Carmichael.”
“Shall we say deed right, sir?” Carmichael suggested with an odiously pawky grin.
“We shall do nothing of the sort, Carmichael. Sit down.”

“It’s a horrid picture that begins to emerge, isn’t it?” Alleyn said as he eased the diary out of the sponge-bag and laid it with elaborate care on a folded towel. “The body is lashed to the cyclist’s back and over it is dragged the dull magenta gown, hiding the cord. The arms are pulled round his waist and the wrists tied. The head, one must suppose, lolls forward on the rider’s shoulder.
“And if anyone was abroad in the night on the road from Crossdyke to Ramsdyke they might have seen an antic show: a man on a Route-Rocket with what seemed to be either a very affectionate or a very drunken rider on his pillion: a rider whose head lolled and jerked preposterously and who seemed to be glued to his back.”
“What about the suitcase?” asked Tillottson.
“Made fast. It’s not weighted at this stage. The stones were collected at the weir.”
“Roadside heap,” Fox put in. “Loose brick. Shingle. We’ve got all that.”
“Exactly, Br’er Fox. Fish out a sponge from my bag, would you?”
Fox did so. Alleyn pressed it over the surfaces of the diary, mopping up the water that seeped out. “It’s when he gets to Ramsdyke,” he went on, “that the cyclist’s toughest job begins. Presumably he’s single-handed. He has to dismount, carry his burden, a ghastly pick-a-back, presumably, down to the weir. He unlooses and dumps it, returns for the case, puts in the stones and shingle, humps the case to the body, adds a loose half-brick, ties the body to the case and pushes both of them far enough along the footbridge to topple them into the weir.”
“Do I,” Fox blandly inquired, “hear the little word conjecture?”
“If you do you can shut up about it. But you don’t hear it all that clearly, old boy. Find me another theory that fits the facts and I’ll eat the dust.”
“I won’t give you the satisfaction, Mr Alleyn.”
“Find something to slide under the diary, will you? I want to turn it over. A stiff card will do. Good. Here we go. Now, the sponge again. Yes. Well, from here, the sinister cyclist and his moll begin to set-up their disappearing act. All we know is that they had paid their bill at the Star and that they lit off some time that night or early next morning. Presumably with a fabulous Fabergé bibelot representing the Signs of the Zodiac in their possession.”
“Hi!” Tillottson ejaculated. “D’you reckon?”
“This really is conjecture,” Alleyn said. “But I don’t mind betting we do not find the damned jewel on board the Zodiac.”
“River bed? Swept of the body, like?”
“I don’t see him leaving it on the body, you know.”
“I suppose not. No.”
“It may have been the motive,” Fox said. “If it’s all that fabulous.”
“Or it may have been a particularly lush extra: a kind of bonus in the general scheme of awards.”
