Sally walked up the steps.

"Oh, don't send her in all alone!" begged Josephine. "Think, what if there should be—"

"The skeleton in armour," urged Bob.

"Go on, Sally, you're game," and Max grinned at Josephine and Bob. "It doesn't take much to rouse some people's imaginations. Go ahead, and confront the seed catalogues and the beetles with a bold front."

Jarvis, smiling at Sally and taking note of her pink cheeks, detained her with an injunction. "Whatever you find," he stipulated, "make no outcry. Retain your composure. Remember your friends are close at hand. Three raps on the inside of this door will summon four stout retainers to your side. Are you ready?"

"Ready."

"Remember that defunct beetles are harmless, old clothes retain no characteristics of their former owners, no matter how blood-thirsty, and empty bottles probably never contained fatal potions. If the place is dark, press your finger on this"—he thrust a small electric search-light into her hand—"and the mystery will be illumined. Brave lady, enter!"

He opened the door just wide enough to admit the slim figure in black, which slipped through and promptly closed the door upon itself.

Josephine interfered.

"Jarvis, don't let her shut that door! Something might happen! There might be a—hole in the floor."
