“Good! Got an outfit?”

“Yes, two of ’em—my brother and I have. We’re gettin’ to be experts. My brother’s better’n I am. We got interested in wireless during the war, reading about how amateurs helped the government spot wireless spies.”

Smithers listened eagerly to Guy’s statement and asked him a good many questions. The latter was an enthusiast and was glad to keep the discussion going as long as his companion did not appear to be bored.

“How’re you getting along with your doctor?” inquired the man finally after they had exhausted the wireless subject.

“I congratulate you. How long do you expect to remain in London yet?”

“Two or three weeks.”

“Going back to New York direct?”

“Yes.”
