He sniffed to right and left, exploring the floor rubbish with inquiring muzzle, and circling the despoiled writing desk.
It was then that Garretse called attention to him.

And it was then that Lad's nose suddenly pointed skyward.

In another moment, he had bounded eagerly toward one of the windows,--the window that was slightly open from the top.
From that direction, the scent now came; and it was more potent than at any earlier time in his quest.
Even as the astonished eyes of the group followed Lad window-ward, those same eyes were attracted by a partial darkening of the open space at the window's top.
Into the room, through the narrow aperture wiggled a hairy form, moving with eel-like speed.
Thence, it leaped to the floor.

For the fraction of a second, the intruder crouched there; peering about, to determine into what company his jump had landed him.
He was a gray monkey, small, infinitely aged and withered of aspect.
His paws and forearms were black with half-dry ink.

Here and there, all over his fuzzy gray body, ink-blobs were spattered.
