John Briggs, a wealthy, ageing confectionery company owner, is found dead in his London hotel suite. Nikki joins forces with Jack to prove to sceptical DS Gold that it’s murder, not death by natural causes. Several suited sharks circle as it transpires Briggs was losing a desperate fight to prevent the sale of his ailing company to investors. And Michael Trenter, his PR man, is unable to conceal Briggs’ murky private life from the baying press, devaluing the family brand by the hour. Meanwhile, Geraldine, Briggs’ estranged daughter, is a fish out of water as she’s left control of the company in her father’s will. Leo is left in no doubt about how to secure the Lyell Centre’s future – by employing Jack to head up a new forensics department. And just as the new team are cemented, crucial evidence from a discovered body gives them a shocking lead on the killer’s motive.
