Over drinks in a public house, Darger displayed his box and explained his intentions for it. Surplus warily touched the intricately carved teak housing, and then drew away from it. “You outline an intriguing scheme, Master Darger—”

“Please. Call me Aubrey.”

“Aubrey, then. Yet here we have a delicate point. How shall we divide up the . . . ah, spoils of this enterprise? I hesitate to mention this, but many a promising partnership has foundered on precisely such shoals.”

Darger unscrewed the salt cellar and poured its contents onto the table. With his dagger, he drew a fine line down the middle of the heap. “I divide—you choose. Or the other way around, if you please. From self-interest, you’ll not find a grain’s difference between the two.”

“Excellent!” cried Surplus and, dropping a pinch of salt in his beer, drank to the bargain.

It was raining when they left for Buckingham Labyrinth. Darger stared out the carriage window at the drear streets and worn buildings gliding by and sighed. “Poor, weary old London! History is a grinding-wheel that has been applied too many a time to thy face.”

“It is also,” Surplus reminded him, “to be the making of our fortunes. Raise your eyes to the Labyrinth, sir, with its soaring towers and bright surfaces rising above these shops and flats like a crystal mountain rearing up out of a ramshackle wooden sea, and be comforted.”

“That is fine advice,” Darger agreed. “But it cannot comfort a lover of cities, nor one of a melancholic turn of mind.”

“Pah!” cried Surplus, and said no more until they arrived at their destination.

At the portal into Buckingham, the sergeant-interface strode forward as they stepped down from the carriage. He blinked at the sight of Surplus, but said only, “Papers?”

Surplus presented the man with his passport and the credentials Darger had spent the morning forging, then added with a negligent wave of his paw, “And this is my autistic.”
