The Irregular by H.B. Lyle (Hardcover)
London 1909: The British Empire spans the globe, seen as an invulnerable imperial power–but in Russia, there is revolution in the wind; in Germany, an arms race; and in London, the streets are alive with foreign agents provocateur.
Vernon Kell, head of counterintelligence at the war office, wants to set up a Secret Service, an agency with a mandate to act domestically and abroad to protect the Empire, but to convince his political masters he needs proof of a threat. To find that proof, he needs an agent he can trust who is smart, ruthless, and able to blend in with the hoi polloi. The playing fields of Eton may produce good army and naval officers, but not men who can work undercover in a munitions factory that appears to be leaking secrets to the Germans . . .
Tracking down the Russian gang responsible for the murder and assembling a motley network of allies and informants in the process, Wiggins begins to unravel a deadly international conspiracy that reaches far beyond the munitions factory.
