No wonder Miss Howard had suggested “hushing it up.” Now I understood that unfinished sentence of hers: “Emily herself——” And in my heart I agreed with her. Would not Mrs. Inglethorp have preferred to go unavenged rather than have such terrible dishonour fall upon the name of Cavendish.

“There’s another thing,” said John suddenly, and the unexpected sound of his voice made me start guiltily. “Something which makes me doubt if what you say can be true.”

“What’s that?” I asked, thankful that he had gone away from the subject of how the poison could have been introduced into the cocoa.

“Why, the fact that Bauerstein demanded a post-mortem. He needn’t have done so. Little Wilkins would have been quite content to let it go at heart disease.”

“Yes,” I said doubtfully. “But we don’t know. Perhaps he thought it safer in the long run. Someone might have talked afterwards. Then the Home Office might have ordered exhumation. The whole thing would have come out, then, and he would have been in an awkward position, for no one would have believed that a man of his reputation could have been deceived into calling it heart disease.”

“Yes, that’s possible,” admitted John. “Still,” he added, “I’m blest if I can see what his motive could have been.”

I trembled.

“Look here,” I said, “I may be altogether wrong. And, remember, all this is in confidence.”

“Oh, of course—that goes without saying.”

We had walked, as we talked, and now we passed through the little gate into the garden. Voices rose near at hand, for tea was spread out under the sycamore-tree, as it had been on the day of my arrival.
