Battle raised his eyebrows.
“Thinking of leaving us again?” he inquired.
“Not just at present,” laughed Anthony. “By the way what’s upset Isaacstein? He arrived in the car just as I left, and he looked as though something had given him a nasty jolt.”
“Mr. Isaacstein?”
“Yes.”
“I can’t say, I’m sure. I fancy it would take a good deal to jolt him.”
“So do I,” agreed Anthony. “He’s quite one of the strong silent yellow men of finance.”
Suddenly Battle leant forward and touched the chauffeur on the shoulder.
“Stop, will you? And wait for me here.”
He jumped out of the car, much to Anthony’s surprise. But in a minute or two, the latter perceived M. Lemoine advancing to meet the English detective, and gathered that it was a signal from him which had attracted Battle’s attention.
