“When the big man came in and landed his aeroplane on the other side of the ridge,” Ben suggested, “he brought two men with him. When we went up in the Louise we saw two men walking about the ledge with lanterns in their hands.”
“One of them may be Colleton!” shouted Carl.
“I don’t know about that,” Jimmie went on, “but I’ll tell you there’s some connection between the bunch that stole Colleton and the bunch the Canadian officers arrested for smuggling whiskey over the Canadian border. I don’t believe the red and green signals we saw night before last were entirely for the benefit of the smugglers. I’ll bet the big man who was killed because he didn’t know how to bring a machine out of an air-hole knew the language of those red and green lights!”
Mr. Havens was assisted back to his tent, and the boys busied themselves getting breakfast. The Englishman wandered about the camp for a long time without speaking. It seemed to the boys that he was studying over the events of the night.
Jimmie even suggested to Carl that the Englishman might be searching his memory for some incident connected with the journey across the continent which would place him in the possession of additional information concerning the man who had been killed.
When breakfast was ready, the Englishman took his seat by the white cloth spread on the grass but ate sparingly.
“Have you lost your appetite?” asked Carl.
“That was quite a shock, don’t you know!” was the answer.
“Are you sure the man we buried is the man who occupied the stateroom on the Pullman-car with the sick man?” asked Ben.
“Quite sure!” was the slow reply.
