"The bottle they were looking for in my dust-bin, what the captain put there after breakfast."

Sheila gave a faint cry.

"What bottle was that, Mrs. Munns?"

"One of them little tablet bottles," said Mrs. Munns, "same as you have standing on the wash-hand stand, Mrs. Fentiman. When I saw the Captain smashing it up in the yard with a poker——"

"There now, Primrose," said Mr. Munns, "can't you see as Mrs. Fentiman ain't well?"

"I'm quite all right," said Sheila, hastily, pushing away the hair which clung damply to her forehead. "What was my husband doing?"

"I saw him," said Mrs. Munns, "run out into the back-yard—just after your breakfast it was, because I recollect Munns was letting the officers into the house at the time. Not that I knew then who it was, for, if you will excuse me mentioning of it, I was in the outside lavatory, and that was how I come to see the Captain. Which ordinarily, you can't see the dust-bin from the house, my lord I should say, I suppose, if you really are one, but you meet so many bad characters nowadays that one can't be too careful—on account of the lavatory standing out as you may say and hiding it."

"Just so," said Wimsey.

"So when I saw the captain breaking the bottle as I said, and throwing the bits into the dust-bin, 'Hullo!' I said, 'that's funny,' and I went to see what it was and I put it in an envelope, thinking, you see, as it might be something poisonous, and the cat such a dreadful thief as he is, I never can keep him out of that dust-bin. And when I came in, I found the police here. So after a bit, I found them poking about in the yard and I asked them what they were doing there. Such a mess as they'd made, you never would believe. So they showed me a little cap they'd found, same as it might be off that tablet-bottle. Did I know where the rest of it was?' they said. And I said, what business had they got with the dust-bin at all. So they said——"

"Yes, I know," said Wimsey. "I think you acted very sensibly, Mrs. Munns. And what did you do with the envelope and things?"
