Five faces with varying degrees of interest were turned to Miss Marple. It may be safely assumed, however, that no one would have guessed the answer to the question right.

‘I saw,’ said Miss Marple impressively, ‘the window of the fishmonger’s shop. There was only one thing in it, a fresh haddock.’

She looked round triumphantly.

‘Oh, my God!’ said Raymond West. ‘An answer to prayer—a fresh haddock!’

‘Yes, Raymond,’ said Miss Marple severely, ‘and there is no need to be profane about it. The hand of God is everywhere. The first thing I saw were the black spots—the marks of St Peter’s thumb. That is the legend, you know. St Peter’s thumb. And that brought things home to me. I needed faith, the ever true faith of St Peter. I connected the two things together, faith—and fish.’

Sir Henry blew his nose rather hurriedly. Joyce bit her lip.

‘Now what did that bring to my mind? Of course, both the cook and house-parlourmaid mentioned fish as being one of the things spoken of by the dying man. I was convinced, absolutely convinced, that there was some solution of the mystery to be found in these words. I went home determined to get to the bottom of the matter.’

She paused.

‘Has it ever occurred to you,’ the old lady went on, ‘how much we go by what is called, I believe, the context? There is a place on Dartmoor called Grey Wethers. If you were talking to a farmer there and mentioned Grey Wethers, he would probably conclude that you were speaking of these stone circles, yet it is possible that you might be speaking of the atmosphere; and in the same way, if you were meaning the stone circles, an outsider, hearing a fragment of the conversation, might think you meant the weather. So when we repeat a conversation, we don’t, as a rule, repeat the actual words; we put in some other words that seem to us to mean exactly the same thing.

‘I saw both the cook and Dorothy separately. I asked the cook if she was quite sure that her master had really mentioned a heap of fish. She said she was quite sure.

‘ “Were these his exact words,” I asked, “or did he mention some particular kind of fish?”

‘ “That’s it,” said the cook; “it was some particular kind of fish, but I can’t remember what now. A heap of—now what was it? Not any of the fish you send to table. Would it be a perch now—or pike? No. It didn’t begin with a P.”

‘Dorothy also recalled that her master had mentioned some special kind of fish. “Some outlandish kind of fish it was,” she said.

‘ “A pile of—now what was it?”

‘ “Did he say heap or pile?” I asked.

‘ “I think he said pile. But there, I really can’t be sure—it’s so hard to remember the actual words, isn’t it, Miss, especially when they don’t seem to make sense. But now I come to think of it, I am pretty sure that it was a pile, and the fish began with C; but it wasn’t a cod or a crayfish.”
