"The Duke asked you to get some supplies for him?"

"No."

"You told him you were going to get them?"

"No. I wanted to surprise him. I wanted to see his face when I turned up with the tins."

Impasse. He could be telling the truth. He could equally well be using the story as a cloak for other and more sinister activities. I couldn't tell and probably would never know. I said: "You better go and tell your friend the Duke that he'll be back on a normal diet as from breakfast."

"You mean-I can go?"

If Mr. Haggerty doesn't wish to press a charge."

I wouldn't lower myself." Haggerty clamped his big hand round the back of Sandy's neck with a grip tight enough to make the little man squeal in pain. "If I ever catch you within sniffing distance of my galley again I won't just squeeze your neck, I'll break the bloody thing." Haggerty marched him to the door, literally threw him out and returned. "Got off far

too easy if you ask me, sir."

"He's not worth your ire, Mr. Haggerty. He's probably telling the truth not that that makes him any less a sneak thief. Moxen and Scott ate here tonight after the passengers had dinner?"

"Every night. Waiting staff usually cat before the guests-they preferred it the other way round." With the departure of Sandy, Haggerty was looking a very troubled and upset man, the loss of two stewards had clearly shaken him badly and was almost certainly responsible for the violence of his reaction towards Sandy.

I think I've traced the source of the poison. I believe the horse-radish was contaminated with a very unpleasant organism called Clostridium botulinum, a sporing anaerobe found most commonly in garden soil."

I'd never heard of such a case of contamination but that didn't make it impossible. "No possible reflection on you-it's totally undetectable before, during, and after cooking. Were there any leftovers tonight?"

Some. I made a casserole for Moxen and Scott and put the rest away."

"Away?"

"For throwing. There wasn't enough to reuse for anything."

"So it's gone." Another door locked.

"On a night like this? No fear. The gash is scaled in polythene bags,

then they're punctured and go over the side-in the morning."

The door had opened again. "You mean it's still here?"

"Of course." He nodded towards a rectangular plastic box secured to the bulkhead by butterfly nuts. "There."

I crossed to the box and lifted the lid. Haggerty said: `You'll be going to analyse it, is that it?"

"That's what I intended. Rather, to keep it for analysis." I dropped the lid. "That won't be possible now. The bin's empty."

"Empty? Over the side-in this weather?" Haggerty came and unnecessarily checked the bin for himself. "Bloody funny. And against regulations."

"Perhaps your assistant-"

"Charlie. That bone-idle lay about. Not him. Besides, he's off-duty tonight ." Haggerty scratched the grey bristle of his hair. "Lord knows why they did it but it must have been Moxen or Scott."

"Yes," I said. "It must have been."

I was so tired that I could think of nothing other than my cabin and my bunk. I was so tired that it wasn't until I had arrived at my cabin and looked on the bare bunk that I recalled that all my blankets had been taken away for Smithy and Oakley. I glanced idly at the small table where I'd left the toxicological books that I had been consulting and my tiredness

very suddenly left me.

The volume on Medical jurisprudence that had provided me with the information on the aconitine was lying with its base pressed hard against the far fiddle of the table, thrown there, of course, by one of the violent lurches of the Morning Rose. The silken bookmark ribbon attached to the head of the book stretched out most of its length on the table, which was an unremarkable thing in itself were it not for my clear and distinct recollection that I'd carefully used the bookmark to mark the passage I'd been reading.

I wondered who it was who knew I'd been reading the article on aconitine.

I suddenly didn't fancy my cabin very much any more. Not, that was, as a place to sleep in. The eccentric shipping millionaire who'd had the Morning Rose completely stripped and fitted for passenger accommodation had had a powerful aversion to locks on cabin doors and, having had the means and the opportunity to do so, had translated his theories into practice. It may have been just a phobia or it may have stemmed from his assertion that many people had unnecessarily lost their lives at sea through being trapped in locked cabins as their ships went down-which, in fact, I knew to be true. However it was, it was impossible to lock a cabin door in the Morning Rose from the inside: it didn't even have a sliding bolt.

The saloon, I decided, was the place for me. It had, as I recalled, a very comfortable corner bulkhead settee where I could wedge myself and, more importantly, protect my back. The lockers below the settee seats had a splendid assortment of fleecy steamer rugs, another legacy, like the lockless doors, from the previous owner. Best of all, it was a brightly lit and public place, a place where people were liable to come and go even at that late hour, a place where no one could sneak up on you unawares. Not that any of this would offer any bar to anyone so ill-disposed as to take a pot shot at me through the saloon's plate-glass windows. It was, I supposed, some little consolation that the person or persons bent on mayhem had not so far chosen to resort to overt violence, but that hardly constituted a guarantee that they wouldn't: Why the hell couldn't the publishers of reference books emulate the prestigious Encyclopaedia Britannica and do away with bookmarks altogether?

It was then that I recalled that I'd left the board of Olympus Productions in full plenary session up in the saloon. How long ago was that?

Twenty minutes, not more. Another twenty minutes, perhaps, and the coast would be clear. It wasn't that I harboured any particular suspicion towards any of the four: they might just consider it very odd if I were to elect to sleep up there for the night lien I'd a perfectly comfortable cabin down below.

Partly on impulse, partly to kill some of the intervening time, I decided to have a look at the Duke, to check on his condition, to ensure him a restful night by promising he'd be back on full rations come breakfast time and to find out if Sandy had been telling the truth. His was the third door to the left: the second to the right was wide open, the door stayed back at ninety degrees. It was "Mary Stuart's cabin and she was inside but not asleep: she sat in a chair wedged between table and bunk, her eyes wide open, her hands in her lap.

"What's this, then," I said. "You look like someone taking part in a wake."

"I'm not sleepy."

"And the door open. Expecting company?"

I hope not. I can't lock the door."

"You haven't been able to lock the door since you came aboard. It doesn't have a lock."

I know. It didn't matter. Not till tonight."

"You-you're not thinking that someone might sneak up and do you in while you're sleeping?" I said in a tone of a person who could never conceive of such a thing happening to himself.

I don't know what to think. I'm all right. Please."

"Afraid', Still – I shook my head. "Shame on you. Think of your namesake, young Mary darling. She's not scared to sleep alone."

"She's not sleeping alone."

"She isn't? Ah, well, we live in a permissive age."

"She's with Allen. In the recreation room."

"Ah! Then why don't you join them? If it's safety you wrongly imagine you need, why then, there's safety in numbers."

I do not like to play-what do you say-gooseberry."

"…Oh, fiddlesticks!" I said and went to see the Duke. He had colour, not much but enough, in his cheeks and was plainly on the mend. I asked him how he was.
