SOME MURDERS CAN'T BE SOLVED IN JUST ONE LIFETIME. From the No 1 bestselling author, a brand new series with a brand new heroine to fall in love with. Ali Dawson is as memorable as her fire-engine-red hair - warm, funny, forthright - and mother to a grown son, Finn.

Ali works on cold cases, crimes so old, the joke goes, that they are almost frozen. What most people don't know is that Ali and the team travel back in time to complete their researches - a process pioneered by the mysterious Italian physicist, Serafina Pelligrini. So far the team has only ventured a few years or decades back but Ali's boss has a new assignment for her.

He wants her to step back to 1850, the heart of the Victorian Age, to clear the name of Cain Templeton, the eccentric ancestor of Tory MP Isaac Templeton, her son Finn's boss. To ready herself for the challenge ahead, Ali researches the Victorian era. She learns that Cain Templeton was part of a sinister group called The Collectors, the rumour being that you had to kill a woman to become a member.

Duly prepared, she arrives in London in January 1850 - the middle of a freezing winter. She is directed to a house inhabited by artists, and is greeted by a dead woman at her feet. Soon she finds herself in extreme danger.

Even worse - she appears to be stuck, unable to make her way back to the present, to the life she loves and to her son, Finn. The Frozen People is a lavish, cleverly plotted mystery with a cast of unforgettable new characters to get to know and love.
