tory the fellow was aiming straight
at it."

"Well, they're not here. See for yourself."

She was right. There was no evidence whatever that any bullets had
passed through the partition. They covered every inch of the cross
wall in their search.

"Lindsay must have been mistaken," decided Whitford, hiding his keen
disappointment. "This man Collins couldn't have been firing in this
direction. Of course everything was confusion. No doubt they shifted
round in the dark and--"

He stopped, struck by an odd expression on the face of his daughter.
She had stooped and picked up a small fragment of shaving from the
floor. Her eyes went from it to a plank in the partition and then back
to the thin crisp of wood.

"What is it, honey?" asked Whitford.

The girl turned to Muldoon, alert in every quivering muscle. "That
express wagon--the one leaving the house as we drove up--Did you notice
it?"

"Number 714," answered Tim promptly.

"Can you have it stopped and the man arrested? Don't you see? They've

Muldoon was out of the room and going down the stairs before she had
finished speaking. It was a quarter of an hour later when he returned.
Beatrice and her father were not to be seen.

From back of the partition came an eager, vibrant voice. "Is that you,
Mr. Muldoon? Come here quick. We've found one of the bullets in the

The policeman passed out of the door through which Bromfield had made
his escape and found another small door opening from the passage. It

"What about the express wagon?" asked Whitford.

"We'll get it. Word is out for those on duty to keep an eye open for
it. Where's the bullet?"

Beatrice pointed it out to him. There it was, safely embedded in the
plaster, about five feet from the ground.

"Durand wasn't thorough enough. He quit too soon," said the officer
with a grin. "Crooks most always do slip up somewhere and leave
evidence behind them. Yuh'd think Jerry would have remembered the
bullet as well as the bullet hole."

They found the mark of the second bullet too. It had struck a
telephone receiver and taken a chip out of it.

They measured with a tape-line the distance from the floor and the side
walls to the place where each bullet struck. Tim dug o
