“Sir Edward was right,” Day said. “At least, I think he was. By the way, where were you?”
“Me? I waited for a bit at Scotland Yard, then followed you out here.”
“Why didn’t you come with the sergeant?”
“I never saw him leave Sir Edward’s office,” March said.
“Well, it’s good to have you here now,” Day said.
“Take a look at this, Inspector,” Hammersmith said. He had knelt on the road and was pointing to the spot where March had been looking.

“Shall we follow it?”
“It may be a waste of time.”
“On the other hand…”
Hammersmith stood and held out his hand to Day, pulled him to his feet, and they set off moving slowly away from the prison, their lanterns held high. March hesitated a moment, then drew his revolver and followed them into the high grass.
