“Good,” Wax said, digging into his pocket and removing a small steel sheet, engraved on one side. His credentials, proof that he was a constable. “I’m on constabulary business. How many of these coaches do you have?” Wax nodded toward the line.

Cett’s expression fell as he realized Wax wasn’t likely to be paying him for anything tonight. “Twenty-three,” the man finally said.

“Lots of coaches still in service for the night,” Wax said. “Considering the hour.”

“We work as long as people are out, constable,” Cett said. “And tonight, people are out.”

Wax nodded. “I need a list of the drivers who are still working, their routes, and any prearranged clients they picked up today.”

“Of course.” Cett seemed more relaxed as he led Wax toward a small building in the center of the carriage yard. As they walked, a coach arrived—no scraped sides—drawn by a pair of sweaty horses with drooping heads and a bit of froth at the mouths. Long hours for the beasts too, it seemed.

Inside the building, Cett fetched some records from a desk. Too eager, Wax thought as the man hurried over and offered them. Whenever someone worked with the authorities too easily, it made Wax’s eye twitch. So he took his time browsing through the lists Cett proffered and kept an eye on the man as he did so. “What percentage of your pickups are impromptu, and what percentage are arranged ahead of time?”

“Half and half, for the black coaches,” Cett said. “The open carriages are more spur-of-the-moment.” He had a good game face, but something was bothering him. What was he hiding?
