A Murder in Time

Kendra Donovan is an FBI agent on the rise until a raid goes wrong. Half her team is killed, a mole is exposed inside the Bureau, and she is badly wounded. After she heals, she abandons orders and flies to England, intent on killing the man she holds responsible for the deaths.

An unexpected assassin pursues her there, and she ducks into a stairwell at Aldrich Castle. When she steps out, the castle is the same but the year is 1815. The household takes her for a lady's maid hired to help with weekend guests, and she has to play the part while she works out how she got there and how to get home.

Then the body of a young girl is found on the grounds of the county estate. A serial killer is at large, and Kendra begins to suspect her arrival is no accident. She has none of her twenty-first century tools, only her training and her wits, and the killer is cunning.

The book is a time-travel mystery that mixes a modern crime investigator with a Regency country-house setting. The danger is real from the start, since the killer threatens her life two centuries before she was born.
