The Secret Detective Agency: A totally gripping historical English cozy murder mystery

Meet Miss Jane Treen - the coffee-drinking cat lover dressed head to toe in tweed, who just happens to be a secret super sleuth!

London, 1941: Miss Jane Treen is at her desk, strong black coffee in hand and fluffy ginger cat by her side, when her top-secret government work is interrupted by an urgent call to Devon. A woman has been found dead in a lake in a place where she shouldn’t have been. Jane needs to gather the clues and find the killer before someone else from the agency gets hurt...

Shy and handsome code-breaker Arthur Cilento is bewildered by the arrival of the efficient Miss Treen and her cat Marmaduke. She bursts into his life unexpectedly, forcing him out of his comfort zone. Placed at his country home to unravel the mystery, together, the reluctant colleagues huddle near the warmth of a crackling fire to piece together the murderous puzzle at hand.

In the sleepy Devon village, someone is hiding something: but is it the busybody vicar and his sister, the dutiful housekeeper and her secretive son, the stern librarian, or someone else altogether? And who were the people with the woman in the lake on the day she died?

No sooner have Arthur and Jane have drawn up a list of suspects, than a parcel reveals a clue that sends them in hot pursuit of a coded diary stashed in a village church. But as the heavy wooden door slams behind them and a key turns in the lock, one thing is sure: they need to unravel the truth and crack this code before the killer decides their number is up...

But if they can catch the culprit in time, might this unusual pair become the finest crime solving partnership since Sherlock and Watson hung up their hats...?
