Don't miss THE BOOKSELLER, the brand new DS Cross Thriller - available now.

'George Cross is becoming one of my favourite detectives.’ ELLY GRIFFITHS

To find a murderer, you need a motive . . .

THE CASE

DS George Cross is called to investigate when the body of a monk is found savagely beaten in a woodland near Bristol.

THE QUESTION

Nothing is known about Brother Dominic’s past. How can Cross unpick a crime when he doesn’t know anything about the victim? And why would someone want to harm a monk?

THE PAST

They learn that Brother Dominic had no enemies – or, at least, none that are obvious. But his past reveals that he was once a wealthy man, that he sacrificed it all for his faith.

For a man who has nothing, it seems strange that greed could be the motive for his murder. But greed is a sin after all . . .

Perfect for fans of MW Craven, Ann Cleeves and Joy Ellis, The Monk is part of the DS George Cross thriller series, which can be read in any order, by the 2025 Crime Writers' Association Dagger in the Library Award longlistee.

'The ultimate conjuring trick: an absorbing plot with an engaging detective I’d follow to the ends of the earth. Just brilliant!' Marion Todd

'A brilliantly old-school detective with a modern twist . . . from the complex emotion of his private life to the razor-sharp detail of the police investigation. Spot on!' Russ Thomas

‘Another tour de force . . . If you're looking for a great crime series you can't do much better than this. George Cross is an absolute delight.’ Bishop Stortford Independent
