titude of a person she called 'Charles' which had
caused all the trouble. Of course I didn't know who Charles was! But
after that she said something which interested me enormously. She
described a visit to a crystal-gazer, or a medium of some kind, and she
said the woman saw 'Charles' lying ill in bed, with a nurse beside him
and a doctor. And who do you think she said the doctor was?
Sartorius!"

"You don't mean it!"

"You see, I had just come from Sartorius's house. I had gone there
that afternoon to try to get a job. You may imagine how interested I
was to find this woman was a patient of the man I expected to work for.
And then ... I got the idea that both Lady Clifford and the young man
seemed disappointed because the medium didn't see anything further, and
Captain Holliday was very bitter about it and said that Charles would
recover and live to be ninety, which upset the lady very much."

"Do you think at that time..."

"No, I don't. What I believe is that Lady Clifford had no definite
determination to do anything until she heard Holliday say he would
probably be sailing on the 8th. I think it was the certainty of losing
him so soon that drove her to take a positive step. No doubt she knew
a good deal about the doctor through Holliday, and how he might be got
at through his desire to be free from routine. As for him, human life
as such meant nothing whatever to him--I heard him say so. All he
cares for is science."

"Do you think Holliday had anything to do with it?" Roger asked
tentatively, playing with the window-cord.

"I am fairly sure he hadn't, though he may have suspected something.
At the last he was dragged into it quite against his will, or at least
I got that idea. He was in a blue funk, too--simply dying to clear
out."

"Just the same," remarked Roger rather grimly, "our friend Arthur is
not going to be able to skin out of the affair so easily as he thinks.
A wireless has already been sent to the boat he sailed on, and when he
reaches port he'll be detained and sent back here. In any case, he'll
be wanted as an accessory after the act, which may prove an unpleasant
business for him.... Go on, though; tell me how you actually came to
make up your mind that something was wrong."

"I never did make up my mind until it was too late--that was the awful
part! When I think it all over, though, I can see that the thing that
most roused my suspicions--not altogether by itself, but taken
