guard outside the street door.

The Frenchman was greatly excited.

He retreated into the hall and went upstairs again, muttering:

"I must geet zat boy een my powair just as queek as possible. So long as ze
Bradys ees on my track, I may go to ze preeson at any moment. It makes me
nairvous, by gar!"

He took up a position at the head of the stairs, wondering how he could get
the best of the detectives.

Convinced that they knew all about his smuggling business and would arrest
him at the first opportunity, it made him so desperate that he would not
have hesitated to kill both of them.

He had not been standing at the head of the stairs long before he saw Harry
glide into the hall as quietly as a shadow.

The boy was becoming impatient over his partner's long absence and made up
his mind to find him.

Searching the lower hall, he failed to see anything of Old King Brady and
then cautiously made his way upstairs.

The Frenchman saw him coming.

He slipped into the room where the old detective lay.

Raising his finger to his wife, he hissed:

"Hush! He coming up ze stair! Put out ze light--hurry!"

Keeping the door open on a crack when darkness fell upon the room, he
peered out and listened intently.

It was too dark to see anything.

But he heard the young detective's soft footfalls passing the door and he
stepped out into the hall behind Harry.

Slight as the noise was which he made, the boy heard him and turned around,
striving to pierce the gloom with his sight.

La Croix had the boy located.

He suddenly sprang forward with both hands extended, struck against the
boy, clutched him by the throat and knocked him over backward.

A stifled cry escaped Harry.

He was knocked down and struck the floor with a crash.

As his head went back, with the Frenchman's grip on his windpipe, his skull
banged against the door-casing.

He was stunned.

"Lena! Lena!" roared La Croix.

"What is it, Paul?" asked the woman, appearing in the doorway.

"Breeng a light--queek!" he panted.

She struck a match and he saw that Harry was senseless.

With a look of evil triumph on his dark face, the man seized the boy,
dragged him into the room and his wife locked the door.

La Croix bound and gagged Harry.

"Got zem both!" he chuckled.

"What are you going to do with them, Paul?" demanded his wife.

"Do wiz zem? Put zem out of ze way, my dear. Dispose of zem so effectually
