“This way, sir,” said Hodgeman. He crossed to one of the shelves and reached up above his head to pull out an unobtrusive, dun-colored tome, adorned only with the Dorrance coat of arms, a chain argent issuant from a chevron argent upon a field azure.

The book slid out halfway, then came no farther.

Hodgeman looked up at it. Nick looked too.

“Is something supposed to happen?”

“It gets a bit stuck sometimes,” replied Hodgeman. He tugged on the book again. This time it came completely out. Hodgeman opened it, took a key from its hollowed-out pages, pushed two books apart on the shelf below to reveal a keyhole, inserted the key, and turned it. There was a soft click, but nothing more dramatic. Hodgeman put the key back in the book and returned the volume to the shelf.

“Now, if you wouldn’t mind stepping this way,” Hodgeman said, leading Nick back to the center of the library. The couches had moved aside on silent gears, and two steel-encased segments of the floor had slid open, revealing a circular stone staircase leading down. Unlike the library’s brilliant white gaslights, it was lit by dull electric bulbs.

“This is all rather cloak-and-dagger,” remarked Nick as he headed down the steps with Hodgeman close behind him.

Hodgeman didn’t answer, but Nick was sure a disapproving glance had fallen on his back. The steps went down quite a long way, equivalent to at least three or four floors. They ended in front of a steel door with a covered spy hole. Hodgeman pressed a tarnished bronze bell button next to the door, and a few seconds later, the spy hole slid open.

“Sergeant Hodgeman with Mr. Nicholas Sayre,” said Hodgeman.

The door swung open. There was no sign of a person behind it. Just a long, dismal, white-painted concrete corridor stretching off some thirty or forty yards to another steel door. Nick stepped through the doorway, and some slight movement to his right made him look. There was an alcove there, with a desk, a red telephone on it, a chair, and a guard—another plainclothes policeman type like Hodgeman, this time in shirtsleeves, with a revolver worn openly in a shoulder holster. He nodded at Nick but didn’t smile or speak.

“On to the next door, please,” said Hodgeman.

Nick nodded back at the guard and continued down the concrete corridor, his footsteps echoing just out of time with Hodgeman’s. He heard behind him the faint ting of a telephone being taken off its cradle and then the low voice of the guard, his words indistinguishable.

The procedure with the spy hole was repeated at the next door. There were two policemen behind this one, in a larger and better-appointed alcove. They had upholstered chairs and a leather-topped desk, though it had clearly seen better days.

Hodgeman nodded at the guards, who nodded back with slow deliberation. Nick smiled but got no smile in return.

“Through the left door, please,” said Hodgeman, pointing. There were two doors to choose from, both of unappealing, unmarked steel bordered with lines of knuckle-size rivets.
