me little time from the cage in which it's her business to watch the
comings and goings. She's muddled, she palpably prevaricates; so I can't
positively, from her observation, give you an hour. But it was remarked
toward half-past ten that our poor friend was no longer in the club."

"She came straight here; and from here she went straight to the train."

"She couldn't have run it so close," I declared. "That was a thing she
particularly never did."

"There was no need of running it close, my dear--she had plenty of time.
Your memory is at fault about my having left you late: I left you, as it
happens, unusually early. I'm sorry my stay with you seemed long; for I
was back here by ten."

"To put yourself into your slippers," I rejoined, "and fall asleep in
your chair. You slept till morning--you saw her in a dream!" He looked
at me in silence and with sombre eyes--eyes that showed me he had some
irritation to repress. Presently I went on: "You had a visit, at an
extraordinary hour, from a lady--_soit_: nothing in the world is more
probable. But there are ladies and ladies. How in the name of goodness,

accessible practically without challenge. My servant makes love to a
young person employed in the rooms above these, and he had a long bout
of it last evening. When he's out on that job he leaves my outer door,
on the staircase, so much ajar as to enable him to slip back without a
sound. The door then only requires a push. She pushed it--that simply
took a little courage."

"A little? It took tons! And it took all sorts of impossible
calculations."

"Well, she had them--she made them. Mind you, I don't deny for a
moment," he added, "that it was very, very wonderful!"

Something in his tone prevented me for a while from trusting myself to
speak. At last I said: "How did she come to know where you live?"
