“Yes, it all fits in so far. But what does it all mean ? What was really meant to happen at one o’clock in Cabin 17? It can’t be the stabbing of the secretary. There would be no point in timing that for a special hour on a special day in a special place. No, it must have been some kind of appointment and he was on his way to keep it when they knifed him. But who was the appointment with? Certainly not with you. It might have been with Chichester. Or it might have been with Pagett.”

“That seems unlikely,” I objected, “they can see each other any time.”

We both sat silent for a minute or two, then Suzanne started off on another tack.

“Could there have been anything hidden in the cabin?”

“That seems more probable,” I agreed. “It would explain my things being ransacked the next morning. But there was nothing hidden there, I’m sure of it.”
