He sprang up to the front porch and tried the door. It was
locked again, of course. Should he ring the bell and get Rad or
his father down to the door?

And then, of a sudden, the principal mystery of all this affair
bit into Tom Swift's mind. The burglar had made his escape. He
could relieve his father's anxiety later. It was his own
puzzlement of mind that he first wished to ease.

Where was Koku?

Even had the giant been circling the stockade around the shops
he surely must have come up to the home premises by this time.
His keen ears could not fail to hear the buzzers. They were still
going and 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.
