Summary

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. The reluctant colleagues huddle near the warmth of a crackling fire in Arthur's country home, working 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 Holmes and Watson hung up their hats…?

If you love twisty crime novels, top-secret intrigue and the very best of Golden Age mysteries, then you will adore Helena Dixon’s totally gripping cozy novel, perfect for fans of Agatha Christie, T E Kinsey and Verity Bright!

I have quite a few of the books from the Kitty Underhey series and while they aren’t bad they are a bit ‘nice’ and predictable and aren’t always my go to books to listen to.

This new book though is a completely different writing style and is absolutely brilliant. There were multiple options for the ‘who did it’ and the character are really well written. I’ve already pre-preferred the next one anyway.

Great story line - absolutely brilliant

Narration is a little monotonous so concentration is require or you may nod off. Story line could be picked to pieces but if you’re looking for a story to just enjoy then it’s a good listen. It’s good how the individual characters, with their distinct personalities, become a joined unit.

Easy listen

This is a fun book with characters you would not nominal out together, but working together and finally realising each others strengths and weaknesses. With an original plot this was a great listen. The narration from Kristin Atherton was pleasant to listen to and each character definition was easy identify.

I couldn't get in to it as I found the narrator very monotonous. I could not follow the story as I kept wandering off in my brain. Listen to the sample furst. see you you think.
