d without further parley I stepped out upon the roof of the
extension.

As I did so I debated with myself whether the case warranted me or not
in sending for Mr. Gryce. As yet there was nothing to show that the girl
had come to any harm. A mere elopement with or without a lover to help
her, was not such a serious matter that the whole police force need
be stirred up on the subject; and if the woman had money, as she said,
ready to give the man who should discover the whereabouts of this girl,
why need that money be divided up any more than was necessary. Yet Gryce
was not one to be dallied with. He had said, send for him if the affair
seemed to call for his judgment, and somehow the affair did promise to
be a trifle complicated. I was yet undetermined when I reached the edge
of the roof.

It was a dizzy descent, but once made, escape from the yard beneath
would be easy. A man could take that road without difficulty; but a
woman! Baffled at the idea I turned thoughtfully back, when I beheld
something on the roof before me that caused me to pause and ask myself
if this was going to turn out to be a tragedy after all. It was a drop
of congealed blood. Further on towards the window was another, and
yes, further still, another and another. I even found one upon the very
window ledge itself. Bounding into the room, I searched the carpet for
further traces. It was the worst one in the world to find anything
upon of the nature of which I was seeking, being a confused pattern of
mingled drab and red, and in my difficulty I had to stoop very low.

"What are you looking for?" cried Mrs. Daniels.

I pointed to the drop on the window sill. "Do you see that?" I asked.

She uttered an exclamation and bent nearer. "Blood!" cried she, and
stood staring, with rapidly paling cheeks and trembling form. "They have
killed her and he will never--"

As she did not finish I looked up.

"Do you think it was her blood?" she whispered in a horrified tone.

"There is every reason to believe so," rejoined I, pointing to a spot
where I had at last discovered not only one crimson drop but many,
scattered over the scarcely redder roses under my feet.

"Ah, it is worse than I thought," murmured she. "What are you going to
do? What can we do?

"I am going to send for another detective," returned I; and stepping to
the window I telegraphed at once to the man Harris to go for Mr. Gryce.

"The one we saw at the Station?"

I bowed assent.
