Just one moment, Morse!! (The voice of the prosecution: was deafening against his ear.) All right! The identification as it stood, as it stands, may perchance appear a trifle tenuous? But have you – you – any – any – reason for discrediting such identification? And the answering voice in Morse's brain – Morse's voice – was firm and confident Indeed! And if it should please my learned friends I shall now proceed to tell you exactly what did happen between 3 a.m. and 5 a.m. on the morning of Wednesday, the 21s June, in 1859.

Gentlemen! We who are engaged in seeking to reconstruct the course as well as the causation of crime are often tormented by the same insistent thought: something must have happened, and happened in a specific way. All theory, all reconstruction, all probability, are as nothing compared with the simple, physical truth of what actually happened at time. If only… if only…, we say, we could see it all; see it all as it actually happened! Gentlemen, I am about to tell you-

Proceed! said the judge (little 'j').

Chapter Twenty-seven

Standing by the door at the left of the fore-cabin, she could see them both. A reporter, perhaps, would have had them dribbling or vomiting; snoring 'stertorously', certainly. But Joanna was to notice, at that point, only the simple fact, the undramatic circumstance: asleep, the pair of them Oldfield and Musson – only the slight rise and fall of the faded maroon eiderdown that covered them both betraying their fitful breathing. Drunk? Yes, very drunk: but Joanna herself had seen to that. Little or no persuasion required, but the timing important… She smiled grimly to herself, and consulted the little silver time-piece she always kept so carefully about her person: the watch her father had given her on her twenty-second birthday (not her twenty-first) -when some fees had been forthcoming from the London Patent Office. And again, now, her hand closed around the precious watch as if it were a talisman for the success of the imminent enterprise.

Occasionally she spoke quietly – very quietly – to the shifty, silly, spotty-faced youth who stood beside her at the entrance to the cabin: his left hand upon the Z-shaped tiller, painted in alternate bands of red, green, yellow; his right hand (where she had placed it herself!) fondling the bosom of her dress. Twenty-five yards ahead, the horse (rather a good one!) was plodding along a little more slowly now, the wooden bobbins stretched taut along its flanks as it forged forward along the silent tow-path -with only the occasional flap of the waters heard as they slurped against the Barbara Bray, heading ever southwards into the night.

Joanna looked briefly behind her now, at the plaited basket-work that protected the narrow-boat's stern. 'Over a bit more, Tom!' she whispered, as the boat moved into the elbow-bend at Thrupp, just past the village of Hampton Gay. 'And don't forget our little bargain,' she added as she stepped up on to the side, whilst Wootton gently manoeuvred the boat ever closer in towards the right-hand bank.

Wootton would not be celebrating his fifteenth birthday until the February of 1860, but already, in several ways, he was a good deal older than his years. Not in every way, though. Never, before Joanna had come on board at Preston Brook, had he felt so besotted with a woman as he was with her. Exactly, as he knew, the rest of the crew had been. There was something sexually animated, and compelling, about Joanna Franks. Something about the way she flashed her eyes when she spoke; something about the way her tongue lightly licked the corners of her mouth after a plate of mutton chops and peas at some low-roofed tavern alongside the canal; something wickedly and calculatedly controlled about her, as she'd drunk her own full share of liquor – that happily awaited, worry-effacing liquor that all the boatmen (including Wootton) drank so regularly along their journeys. And Oldfield had taken possession of her – of that Wootton was quite sure! Taken her in one of the pitch-black transit-tunnels when he, Wootton, had gladly taken Oldfield's 6d, and 'legged' the Barbara Bray slowly towards that pin-point of light which had gradually grown ever larger as darkly he'd listened to the strangely exciting noises of the love-making taking place in the bunk below him. Towns, too, had taken Oldfield's 6d in a tunnel further south. And both Towns and Musson – the lanky, lecherous-eyed Musson! – knew only too well what was going on, soon wanting a share of things for themselves. No surprise, then, that nasty incident when Towns had gone for Musson – with a knife!

As agreed, Thomas Wootton provided her with the lantern. The night, though dark, was dry and still; and the flame nodded only spasmodically as she took it, and leaped lightly off the Barbara Bray – her bonnet around her head, her shoes on her feet – on to the tow-path bank where, very soon, she had disappeared from the youth who now kept looking straight ahead of him, a smile around his wide, lascivious mouth.

It was not unusual, of course, for women passengers to jump ashore at fairly regular intervals from a narrow-boat: female toiletry demanded a greater measure of decorum than did that for men. But Joanna might be gone a little longer than was usual that night… so she'd said.

She stood back in the undergrowth, watching the configuration of the boat melt deeper and deeper into the night. Then, gauging she was out of ear-shot of the crew, she called out the man's name – without at first receiving a reply: then again; then a third time – until she heard a rustling movement in the bushes beside her, against the stone wall of a large mansion house – and a suppressed, tense, 'Shsh!'

The night air was very still, and her voice had carried far too clearly down the canal, with both the youth at the helm, and the man with the stoical horse, turning round simultaneously to look into the dark. But they could see nothing; and hearing nothing further, neither of them was giving the matter much further thought.

But one of the men supposedly asleep had heard it, too!

Meanwhile Joanna and her accomplice had flitted stealthily along the row of small, grey-stoned, terraced cottages which lined the canal at Thrupp, keeping to the shadows; then, gliding unobserved past the darkened, silent windows of the Boat Inn, they moved, more freely now, along the short hedge-lined lane that led to the Oxford-Banbury highway.

For the Barbara Bray, the next three miles of the Oxford Canal would interpose the Roundham, Kidlington Green, and Shuttleworth's locks – the latter just north of the basin of water known as Duke's Cut. Negotiation of these locks (so carefully calculated!) would afford appropriate opportunity. No real problem. Much more difficult had been the arrangements for meeting each other; and certainly Oldfield, more than once, had looked at Joanna suspiciously in the last twenty-four hours as she had taken (but of necessity!) her diurnal and nocturnal promenades. She knew, though, how to deal with Oldfield, the skipper of the Barbara Bray …

'Everything ready?'

He nodded, brusquely. 'Don't talk now!'

They walked across to a covered carrier's wagon which stood, a piebald horse between its shafts, tethered to a beech tree just beside the verge. The moon appeared fitfully from behind the slow-moving cloud; not a soul was in sight.
