Harris Stuyvesant traveled to London from New York, a semi- disgraced U.S. agent for the Justice Department's Bureau of Investigation. Hoover let him go on this quest to find a bomber who Harris believed was an English Labour Party leader. Although no one else believed the man, Richard Bunsen, was guilty of the bombings, Harris convinced his boss to let him try to get evidence. But Harris was spending his own money and coming up with nothing that tied Bunsen to the bombings.

And then he finally found someone in London's government who could help him, although he couldn't bring himself to trust the man. Aldous Carstairs had no obvious title, clearly doing something within the government that was top secret. But Carstairs said he could introduce Harris to a man, Capt. Bennett Grey, who would get him near Bunsen.

But when Harris meets Grey, he finds a man devastated by war injuries and touting a strange, paranormal talent. Despite his distrust of Carstairs, Harris is immediately drawn to Grey -- but doesn't really know if he can trust either man.

Harris' career rests on finding this bomber, and he can't go home without evidence. So he allies himself with Grey and Carstairs, two men who have a contentious relationship and may not even be able to help.

What a wonderful foray into British mysteries! Ms. King has created a detective worthy of Holmes and yanks the reader subtly and strongly into a Great Britain recreating itself between the World Wars. An intelligent, complex, beautifully written novel.
