the conversation, and was considerably surprised when Kennedy
hung up the receiver and said:

"Vandam had the prescription filled again early this morning, and
it will soon be in the hands of O'Connor. I hope I haven't
spoiled things by acting too soon, but I don't want to run the
risk of a double tragedy."

"Well," I said, "it is incomprehensible to me. First I suspected
suicide. Then I suspected murder. Now I almost suspect a murder
and a suicide. The fact is, I don't know just what I suspect. I'm
like Dr. Hanson--floored. I wonder if Vandam would voluntarily
take all the capsules at once in order to be with his wife?"

"One of them alone would be quite sufficient if the 'ghost'
should take a notion, as I think it will, to walk in the
daytime," replied Craig enigmatically. "I don't want to run any
chances, as I have said. I may be wrong in my theory of the case,
Walter, so let us not discuss this phase of it until I have gone
a step farther and am sure of my ground. O'Connor's man will get
the capsules before Vandam has a chance to take the first one,
anyhow. The 'ghost' had a purpose in that message, for O'Connor
tells me that Vandam's lawyer visited him yesterday and in all
probability a new will is being made, perhaps has already been
made."

We breakfasted in silence and later rode down to the office of
Dr. Hanson, who greeted us enthusiastically.

"I've solved it at last," he cried, "and it's easy."
