ht in Mr. Swift's room. Rad had evidently
gone to sleep again. It would take more than an intermittent buzzer to
rouse fully that colored man.

"When old Morpheus has a strangle hold on Rad, Gabriel's trump would
scarcely awaken him," Tom muttered.

What had become of the enemy? If it was an ordinary burglar he would
have feared the electric alarm instantly. The buzzers were still
working. But there was no sign of the man who had set them off at the
bathroom window.

Suddenly Tom heard a door slam. It was from the front of the house. Had
his father come downstairs to look around and see what the matter was?

The young fellow started around the house on a run. He heard heavy
bootsoles spurning the gravel of the path to the front gate. He arrived
at the far corner of the house in time to see a man dash through the
gateway and run down the street, disappearing finally into the
fast-driving rain.

"Fooled me! He went in and right through and down the stairs! Out the

would go until the switch was turned.

If the giant was in his room--Tom turned suddenly and started on a run
for the rear premises. He still carried the hand-lamp and it lit his
way into the garage door and up the narrow stairway. He shot the round
beam of the lamp into Koku's room.

He had been obliged to have an iron bedstead made to order for the
giant. It stood against one wall of the room. The buzzer was snarling
like a huge bumblebee above the head of the couch. Below it sprawled
the giant, eyes tightly closed and mouth slightly ajar. From the lips
of Koku were emitted sounds worthy of Rad Sampson in his deepest
slumbers!

"Asleep?" gasped Tom, stepping cat-like into the room.

And then he was suddenly aware of a sickish, heavy odor in the chamber.
The window had been closed. But i
