Opening the door into the tiny vestibule of his apartment, he sighed with contentment and relief. After hanging up his hat and coat, he strolled into the living room.

In that impossibly black place eleven luminous, nightmare masks floated suddenly out at him. They gleamed and flickered with an unearthly light all their own. The masks were different, but they were all hideous, all malevolent. Some had huge drooping noses; some, great white rubbery lips, grinning with insane merriment; some had tiny glittering eyes and fearful pink mouths.

For one terrible moment Mr. Apondee stood frozen and speechless. Then he began to scream. He screamed and kept on screaming and shouts of "Surprise!" died in eleven throats which were in turn suddenly stricken silent.

Candles were dropped, and some of the masks, but too late. Mr. Apondee plunged like a maddened thing through the darkened room. He headed for the only glimmer of natural light which was visible—a window.

He hurled himself through it, shade and all, and he was still screaming when he struck the cement walk, seven stories below.

THE VISITOR IN THE VAULT

Newling hated the vault. Hated its shadows, its silence, its cold stale air.

But this morning there could be no escape. Preston Haver's books had been sorted and classified, and Mr. Twais, the head librarian, had given instructions that some of the most valuable of the lot were to be stored in the locked basement vault.

Running his hand through his thinning hair, Newling pushed the book truck into the staff elevator. Mrs. Joy, the desk attendant, watched him with an abstracted expression. There was no one else in sight. Mr. Twais was in his private office, reading the morning mail.

The elevator glided to a smooth stop and Newling rolled out the truck. Fretting with irritation, he started down the long, dimly-lighted corridor which led to the locked vault.
