"Exactly. One thing her evidence _has_ shown me. I made a
mistake. Dorcas was quite right. The quarrel did take place
earlier in the afternoon, about four o'clock, as she said."

I looked at him curiously. I had never understood his insistence
on that point.

"Yes, a good deal that was peculiar came out to-day," continued
Poirot. "Dr. Bauerstein, now, what was _he_ doing up and dressed
at that hour in the morning? It is astonishing to me that no one
commented on the fact."

"He has insomnia, I believe," I said doubtfully.

"Which is a very good, or a very bad explanation," remarked
Poirot. "It covers everything, and explains nothing. I shall
keep my eye on our clever Dr. Bauerstein."

"Any more faults to find with the evidence?" I inquired
satirically.

"Mon ami," replied Poirot gravely, "when you find that people are
not telling you the truth--look out! Now, unless I am much
mistaken, at the inquest to-day only one--at most, two persons
were speaking the truth without reservation or subterfuge."

"Oh, come now, Poirot! I won't cite Lawrence, or Mrs. Cavendish.
But there's John--and Miss Howard, surely they were speaking the
truth?"
