"Heaven and Naida Karetsky," Chalmers intervened softly.
"You believe that she is our enemy?" Nigel asked, with a look of trouble in his eyes.
"She is Immelan's friend," Chalmers reminded him.
"There was a man named Atcheson," Jesson began quietly—
Nigel nodded.
"He was one of the men my uncle sent out. The first one was stabbed in Petrograd. Jim Atcheson was poisoned and died in Berlin."
"There was rather a scare in a certain quarter about Atcheson," Jesson observed. "He was supposed to have got a report through to the late Lord Dorminster."
"He got it through all right," Nigel replied. "My uncle was busy decoding it, seated in this room, at that table, when he died."
"His death was very sudden," Jesson ventured.
"I have not the faintest doubt but that he was murdered," Nigel declared. "The document upon which he was working disappeared entirely except for one sheet."
