"What?" demanded Venza breathlessly.

"Only hints. Why take chances, by repeating them now?"

"You said he wants me, too?" I put in.

"Yes. You and Venza. We've got to get into his office secretly, by the vacuum cylinders. We're to meet a man from his office at the Eighth Postal switch-station."

"Venza?" Anita said sharply. "What in the universe can he want with Venza? If she's going, I'm going too!"

Snap gazed at her and grinned. "That sounds like a logical deduction. Naturally he must want you; that's why he said Venza."

"I'm going," Anita insisted.

We left half an hour before midnight. The girls were both in gray, with long capes. We took the public monorail into the mid-Manhattan section under the city roof of the business district, and into the Eighth Postal switch-station where the sleek bronze cylinders came tumbling out of the vacuum ports to be re-routed and dispatched again.

A man was on the lookout for us. "Daniel Dean and party?"

"Yes. We were ordered here."
