suddenly exclaimed the manager. "I
wonder--"

From his private office, into which he had ushered the colonel, he
looked down the store. It was almost deserted now, save for a few
customers and the clerks.

"It's the same place!" murmured the manager,

"What is?" asked the detective.

"Miss Brill was shocked, and fell at the very spot where the dead body
of Mrs. Darcy was found!" said Mr. Kettridge in a low, intense voice.
"Except for the fact that she fell behind the showcase and Mrs. Darcy
in front of it, the place is the same!"

With a muttered exclamation the colonel got to his feet and also looked
out from the private office.

"You're right," he admitted. "I wonder if that is a coincidence
or--something else. I must go to see Darcy."

The prisoner was measurably startled when the detective told him the
latest development at the jewelry store.

"Those were never my wires in the showcase!" cried the young man. "I
knew some were there, for we did have an antiquated burglar alarm
system when I first came to work for my cousin. I had another one put

used for my lathe experiments had no connection with those, I'm sure.
What is your theory?"

"I have so many I don't know at which one to begin," admitted Colonel
Ashley. "But I was wondering if it was possible that the showcase

and so killing her."

"By _accident_ do you mean?" asked Darcy, his face lighting up with
hope.

"Yes. This young lady received a severe blow on her head by her fall,
and your cousin--"

"You forget the stab wound, Colonel."

"No, I didn't exactly _forget_ it. I was wondering how we could
account for that if we accepted the shock theory. I guess we can't.
I'm still up against it. I've struck a snag--maybe a stone wall,
Darcy!"

"Do you--do you think you can get over it, Colonel?"

"By gad, sir! I will! That's all there is to it! _I will_!"

The silence of the colonel's room was broken by a peculiar scratching
at the door, interrupting his perusal of this passage:

"I told you angling is an art, either by practice or long observation
or both. But take this for a rule--"

"Come in!" invited the colonel, thinking it might be Shag, who
