a friend of Howard Van
Cleft," he continued. "Your three friends have met their deaths at the
hand of a cunning conspirator. Last night, white I talked with you on
the telephone, young Van Cleft was receiving advice over another wire
from a person who pretended to be William Grimsby--advising him to hush
the matter up and drop the investigation. But--Captain Cronin the
famous detective--has received a tip that the number of victims would be
increased very soon--frankly, now: do you want to be the fourth?"
Grimsby's face changed to ashen gray, as he timidly clutched Shirley's
sleeve.
"Then cooperate with me. You understand now the nature of this villain's
work: to rob and assassinate his victim in the company of a girl, so

let your instrument ring unanswered."
"I'll do what I can, if I can keep out of more danger. An old man craves
life more than a young one. I fought through the Civil War and brought
a medal from Congress and this wounded knee out of it, Mr. Shirley. I
didn't fear anything then, but times have changed!"
"Here is my plan, then," continued Shirley, his lips twitching with
sub-strata amusement, "I want to impersonate you, when you leave, so
that this man tries to send me after the other three. Don't interrupt,
let me finish--You will say that it is impossible to deceive any one at
close range. Surely, it does sound melodramatic, like a lurid tale of
a paper back novel. But I have studied the photographs of your friends.
You and I bear the closest resemblance of any in the group. Your weight
is about the same as mine--your shoulders are a trifle stooped and
you walk with a curious drag of your left foot. Your hair is white
but thick: the contour of our
