CHAPTER XXXI
Ambrose announced a visitor, early on the following morning, with some show of interest.
“Captain Granet to see you, sir. We’ve a good many notes about him. Would you like the book?”
Thomson shook his head.
“Thank you,” he answered drily, “I have it in my desk but I think I can remember. Is he outside now?”
“Yes, sir! He said he wouldn’t keep you for more than a few minutes, if you could spare him a short interview.”
“Any luck last night?”
Ambrose sighed.
“I was up till three o’clock again. Once I thought I was on the track of it. I have come to the conclusion now that it’s one of those codes that depend upon shifting quantities. I shall start again to-night on a different idea. Shall I show Captain Granet in, sir?”
