leave, sir."

"To leave?"

The old man struggled to his feet. "No. 712, do you say? Seven
stories," he sighed. But as he turned with a hobble, he stopped.
"There are difficulties in the way of this interview," he remarked.
"A blush is not much to go upon. I'm afraid we shall have to resort
to the shadow business and that is your work, not mine."

But here the door opened and a boy brought in a line which had been
left at the desk. It related to the very matter then engaging them,
and ran thus:

"I see that information is desired as to whether any person was
seen to stoop to the lobby floor last night at or shortly after
the critical moment of Miss Challoner's fall in the half story
above. I can give such information. I was in the lobby at the
time, and in the height of the confusion following this alarming
incident, I remember seeing a lady,--one of the new arrivals
(there were several coming in at the time)--stoop quickly down
and pick up something from the floor. I thought nothing of it at
the time, and so paid little attention to her appearance. I can
only recall the suddenness with which she stooped and the colour
of the cloak she wore. It was red, and the whole garment was
voluminous. If you wish further particulars, though in truth, I
have no more to give, you can find me in 356.

"HENRY A. MCELROY."
