Ada Wren, an interpreter, carries meaning between people who share no language. In each book a job takes her into a closed world where someone dies, and she listens for the place where two languages stop matching.

About E. J. Hartley

E. J. Hartley writes mysteries and thrillers in which the murder weapon is a sentence. Hartley’s narrators are interpreters, bound by a professional rule that reads like a moral one — you do not change what is said — and every book asks what that rule costs when the accurate rendering protects the guilty, or gets somebody killed.
