Sir George leant back in his chair and rumpled his thick grey hair.

“The only person who seems to have remained,” he said with heavy sarcasm, “was Kara himself. Would you like me to put somebody else on this case—it isn't exactly your job—or will you carry it on?”

“I prefer to carry it on, sir,” said T. X. firmly.

“Have you found out anything more about Kara?”

T. X. nodded.

“All that I have discovered about him is eminently discreditable,” he said. “He seems to have had an ambition to occupy a very important position in Albania. To this end he had bribed and subsidized the Turkish and Albanian officials and had a fairly large following in that country. Bartholomew tells me that Kara had already sounded him as to the possibility of the British Government recognising a fait accompli in Albania and had been inducing him to use his influence with the Cabinet to recognize the consequence of any revolution. There is no doubt whatever that Kara has engineered all the political assassinations which have been such a feature in the news from Albania during this past year. We also found in the house very large sums of money and documents which we have handed over to the Foreign Office for decoding.”

Sir George thought for a long time.

Then he said, “I have an idea that if you find your secretary you will be half way to solving the mystery.”

T. X. went out from the office in anything but a joyous mood. He was on his way to lunch when he remembered his promise to call upon John Lexman.

Could Lexman supply a key which would unravel this tragic tangle? He leant out of his taxi-cab and redirected the driver. It happened that the cab drove up to the door of the Great Midland Hotel as John Lexman was coming out.
