a little smile and
bow, he seated himself by the writing table.

"I am very distressed at this happening," he went on, "and I am
more distressed because I feel that as I introduced Lexman to this
unfortunate man, I am in a sense responsible."

"If I were you," said T. X., leaning back in the chair and looking
half questioningly and half earnestly into the face of the other, "I
shouldn't let that fact keep me awake at night. Most people are murdered
as a result of an introduction. The cases where people murder total
strangers are singularly rare. That I think is due to the insularity of
our national character."

Again the other was taken back and puzzled by the flippancy of the man
from whom he had expected at least the official manner.

"When did you see Mr. Vassalaro last?" asked T. X. pleasantly.

Kara raised his eyes as though considering.

"I think it must have been nearly a week ago."

"Think again," said T. X.

For a second the Greek started and again relaxed into a smile.

"I am afraid," he began.

"Don't worry about that," said T. X., "but let me ask you this question.
You were here last night when Mr. Lexman received a letter. That he did
receive a letter, there is considerable evidence," he said as he saw
the other hesitate, "because we have the supporting statements of the

"I should have thought you would," suggested T. X., "because you see,
you burnt the envelope, and I presumed you would have noticed that."

"I have no recollection of burning any envelope," said the other easily.

"At any rate," T. X. went on, "when Mr. Lexman read this letter out to
you..."

"To which letter are you referring?" asked the other, with a lift of his
eyebrows.

"Mr. Lexman received a threatening letter," repeated T. X. patiently,
"which he read out to you, and which was addressed to him by Vassalaro.
This letter was handed to you and you also read it. Mr. Lexman to your
knowledge put the letter in his safe--in a steel drawer."

The other shook his head, smiling gently.

"I am afraid you've made a great mistake," he said almost
apologetically, "though I h
