The Black Gang by H.C. McNeile

The prospect in front of Count Zadowa, alias Mr. Atkinson, was not a very alluring one, and the more he thought about it the less he liked it. Either the diamonds were blown to dust, or they were in the hands of the authorities. In the first event he had the Reverend Theodosius to reckon with; in the second the police. And for preference the police won in a canter.

He was under no delusions was the hunchback. This mysterious man who signed all his communications by the enigmatic letter X, and whose real appearance was known probably only to the girl who was his constant companion, so wonderful and varied were his disguises, was not a person whom it paid to have any delusions about. He paid magnificently, even lavishly, for work well done: for failure he took no excuse. Even long association did not mitigate the offence. With a shudder Count Zadowa remembered the fate of certain men he had known in the past, men who had been employed, even as he was now employed, on one of the innumerable schemes of their chief. No project, from the restoration of a monarchy to the downfall of a business combine, was too great for the man who now called himself the Reverend Theodosius Longmoor. All that mattered was that there should be money in it. Why he should be interesting himself in the spread of Communism in England it was not for Count Zadowa to inquire, even though he was the head of that particular activity. Presumably he was being paid for it by others; it was no business of Count Zadowa's.
