"The number?" said the other. "Oh, yes, to be sure. I have it
in my pocket-book. The rest of the description is accurate, is it?"

"Let me hear the number," said Jack quietly. "Two watches may
be exactly alike, but have different numbers. I have not said
that your description is correct. You have the number?"

"Why, of course!" said the other somewhat impatiently, and all
at once a light broke in upon Jack.

The man was the one he had heard, but had not seen, talking with
the foreign nurse maid on the bank of the kill earlier in the
afternoon.

He had tried to place the man's voice, but while he talked in low,
pleasant tones, with a good inflection, he was puzzled, knowing
and yet not knowing it.

The instant that the man spoke in impatient, angry tones, such
as he had used on the bank of the kill, Jack recognized him, and
he wondered that he had not done so before.

The man took a slip of paper from his pocketbook, and read out a
number written in pencil, the exact number of the watch which Jack
had found.

"Is that correct?" he asked Jack with a certain tone of triumph.

"Perfectly so," the boy answered.
