“Are you aware of the contents of this letter?” asked Washington, drawing the folded sheet of paper back and forth between his fingers.

“Only that the marquis wrote it himself and instructed me to facilitate in every way your return to London on a matter of some importance. We will be leaving at once.”

“Must we? The first through connection on an up train is at nine and it won’t arrive until the small hours.”

“On the contrary,” Drigg said, smiling. “A special run of The Flying Cornishman has been arranged for your convenience and should be now waiting.”

“It is that urgent then?”

“The utmost, his lordship impressed that upon me most strongly.”

“All right then, I will have to change…”

“Permit me to interrupt. I believe instructions were also sent to the head porter of your hotel and a packed bag will be awaiting aboard the train.”

Washington nodded acceptance; the decision had been made. He turned about and raised his voice over the growing din. “Bullhead. You will be head ganger here until Fighting Jack returns. Keep the work moving.”

There was no more to be done. Washington led the way back through the shield to the electric locomotive which he commandeered for the return trip. They took it as far as the bulkhead and arrived just in time to meet Fighting Jack emerging from the air-lock door.

“Damn me if I want to do that again,” he bellowed, his clothes still dripping wet, bruises on his head and shoulders where he had been dragged through the ocean bottom. “Like a cork in a bung I was, stuck and thought it me last moments. Then up like a shot and everything getting black and the next I know I’m looking up’t‘sky and at the faces of some ugly sinners and wondering if I were’t’heaven or the other place.”
