The Steinberg Diamonds

The Steinberg Diamonds


The lives of two ordinary people are about to change forever.


Scrambling around in a dusty back room of a former undertaker’s shop in Cardiff Docks, Pat Doyle stumbles across a cryptic letter. A letter that is about to change his life... or possibly end it, and that of his new-found love, Demi.


Cardiff, fifty years earlier. A fortune in diamonds, stolen from a train by a nefarious small-time crook, is hidden and lost after the thief’s untimely death. Pat deciphers the letter, locates the lost fortune and sees this as the way out of his mundane, debt-ridden life as a social worker. Will this find be the passport to a better life? Maybe… but there are others who lay claim to the stones, and they won’t give up easily...


Cardiff gangster Barry Laine is prepared to do whatever it takes to get his hands on the diamonds. Abraham Steinberg, the son of the original owner, wants them returned to his family, but is no match for Laine. Step in ex-Mossad assassin Ben Wiener – the ultimate arbiter who gets things done, and doesn't care how he does it...


Follow Pat and Demi as they try to outrun and outwit Laine in a race to stay alive – a race they must win. The prize is a life together in paradise... but is it a risk worth taking?


A riveting story of family, greed, death, and love that moves from Cardiff to London, across Europe and reaches a dramatic conclusion on a yacht in the Bristol Channel.
