"I said I would do it. But it was terribly conspicuous. Everybody would
notice when it was gone. He said I must conceal it anyhow until we
unmasked after supper, and then I could pretend I had lost it. He
discussed several plans for having me slip it to him, but it was Aileen
who insisted we should come here. Mrs. Thornton never opens her boudoir
at a party. Everywhere else would be a blaze of light. In this dark
corner we should be safe, especially if he came from the outside and I
from inside. How did your detective find out?"
"I think Aileen did a decent thing for once in her life."
She went on in her monotonous voice. "I felt reckless after that and I
really was gay and almost happy at dinner last night. The die was cast. I
didn't much care for anything. I thought perhaps it was my last night
with you--that when I told you I had lost the ruby you would suspect and
turn me out of your house, tell maman to take me back to Rouen.
"Then came that awful moment when you said you had to go away and I could
not wear it. For a few moments I thought I should scream and tell you
everything. But I was both too proud and too much of a coward. Then I
knew I should have to rob the safe, and somehow I hated that part more
than anything else. I did it just ten minutes before Rex and Polly called
for me to motor down here. It had seemed the most horrible thing in the
world to be a gambler, but it was worse to be a thief.
"I remembered the combination perfectly. I have that sort of memory: it
registers photographically. I had seen you move the combination several
times. Perhaps I deliberately registered it. I can't say. I have lived in
such a maze of intrigue lately. I can't say. That is all--except that I
didn't get the letters and the other things."
"He had an envelope in one hand. Spaulding has it beyond a doubt."
