The detective gazed at the girls and at me. "It was three, Dean."
"And now it's four," said Snap cheerfully. "The extra one is Miss Anita Prince. Ever heard of her?"

We were put into one of the oversized mail cylinders and routed through the tubes like sacks of recorded letters; in ten minutes, with a thump that knocked the breath out of all of us, we were in the switch-rack of Halsey's outer office.

The guard stood aside. "Come in."
The door slid down behind us. We advanced into the small blue-lit apartment, steel-lined like a vault.
