n make up the amount,
and then--"

"Then what?"

A sweet soft look robbed her face of its piquancy, but gave it an aspect
of indescribable beauty quite new to Arthur's eyes.

Tapping his lips with a thoughtful forefinger, he asked:

"Who was that sombre-looking chap I saw bowing to you as we came out of
church last Sunday?"

She awoke from her dreamy state with an astonishing quickness.

"He? Surely you remember him. Have you forgotten that evening in
Massachusetts--the grotto--and--"

"Oh, it's Upjohn, is it? Yes, I remember him. He's fond of church, isn't

Her lips took a roguish curve then a very serious one; but she made no

Only do be careful, Violet. A man so melancholy will need a deal of

clock ticking out its inexorable reminder.

"He will want an answer the first thing in the morning," she complained
to herself. And opening the packet, she took out first a letter, and
then a mass of typewritten manuscript.

She began with the letter which was as characteristic of the writer as
all the others she had had from his hand; as witness:

You probably remember the Hasbrouck murder,--or, perhaps, you don't;
it being one of a time previous to your interest in such matters. But
whether you remember it or not, I beg you to read the accompanying
summary with due care and attention to business. When you have well
mastered it with all its details, please communicate with me in any
manner most convenient to yourself, for I shall have a word to say to
you then, which you may be glad to hear, if as you have lately intimated
you need to earn but one or two more substantial rewards in order to
cry halt to the pursuit for which you have proved yourself so well
qualified.

The story, in deference to yourself as a young and mu
