never entertained the idea that there were two.
Steel, you are the victim of a vile conspiracy, but it is nothing to the
conspiracy which has darkened my life."

"Sooner or later I always felt that I should get to the bottom of the
mystery, and now I am certain of it. And, strange as it may seem, I
verily believe that you and I are hunting the same man down--that the one
man is at the bottom of the two evils. But you shall hear my story
presently. What we have to find out now is who was the last tenant and
who is the present owner of the house, and incidentally learn who this

Bell spoke exultingly, a great light shining in his eyes. And David
sapiently asked no further questions for the present. All that he wanted
to know would come in time. The next move, of course, was to visit the
agent of the property.

A smart, dapper little man, looking absurdly out of place in an

Bell listened eagerly. Watching him, David could see that his eyes
glinted like points of steel. There was something subtle behind all this
common-place that touched the imagination of the novelist.

"Has 218 been let during the occupation of the present owner?"
Bell asked.

"No," the agent replied. "But the present owner--as heir to the
property--I am told, was interested in both 218 and 219, which used to be
