Death with a double edge / Anne Perry.

"It is May 1911 when Daniel Pitt is summoned to a murder scene in the slums of London's East End. He fears the victim is his friend Toby Kitteridge, but relief is quickly followed by dismay when Daniel identifies the dead man as Jonah Drake, a distinguished senior barrister who has been killed with a double-edged sword. But what was Drake doing in Mile End? And does their head of chambers, Marcus fford Croft, know more than he is willing to admit? With the police holding out little hope of finding Drake's killer, Daniel and Kitteridge rise to the challenge. Within days, they have leads that take them from the underbelly of the East End to the very highest echelons of society. Then Daniel's father, Thomas Pitt, receives a warning from Special Branch to cease the investigation. But Daniel and his father will not be deterred - despite the risks involved in the pursuit of justice . . ."--Publisher.
