The Spies of Hartlake Hall is a compelling read that will keep you guessing from the beginning to end.

It is very much like an Agatha Chrisite closed door mystery and I can think of no other great compliment.

It is WW1 and a body is discovered in a locked room with a stolen code in his pocket that very few know about.

Patrick Gallagher is summoned to investigate and along with Mrs Vance the duo are determined to whittle down the vast list of suspects.

Who can they trust or believe.

Invitations go out to Hartlake Hall where all the suspects will gather.

R. L. Graham is a wonderful story teller and presents the reader with twists and turns, red herrings, characters you love, those you snarl at.

I highly recommend you grab your copy of The Spies of Hartlake Hall and settle in for a gripping read.

Thanks to NetGalley and Pan Macmillan/Macmillan for introducing me to this great series and I cant wait for Patrick Gallagher's next adventure.

1917 A body is discovered in a locked room, with a telegram from the German Foreign Ministry. Patrick Gallagher of the British Secret Service, is called in to investigate, and so the possible suspects are invited to his family's current home, Hartlake Hall. Then it gets complicated.
An entertaining and interesting well-written historical spy mystery with its cast of diverse characters.
An ARC was provided by the publisher via Netgalley in exchange for an honest review.

Did i know what was going to happen at any point in time? Not a chance. It was a ride from start to finish and it was one you're going to want to ride over and over again.

I found The Spies of Hartlake Hall to be a gripping historical crime mystery set in World War I, with a locked‑room‑style investigation at a country manor, shadowy spies, and plenty of intrigue that kept me turning the pages.
