If You’re Watching This

‘If You’re Watching This . . . then I’m already gone. Probably murdered. I know you won’t be upset about that, Kezuma. But unfortunately, now that I am not here, you and your family are in grave danger. The only way to keep them safe is to take my place at Insight then find out who killed me.’

After Dr Kez Lanyon’s boss Dennis Chambers is murdered, she finds out just how much he looked out for her and just how much danger she is now in. Her only option is to find his killer – by fighting the powers that be to take a job she doesn’t want in a place she hates.

When someone claiming to be Dennis’s long-lost daughter arrives, eager to find out about her father’s life and death, Kez is forced to take her in to protect her, too. But can she trust this young woman who shows all the signs of being a dangerous psychopath like her father? And how will Kez navigate a high-level job where more than one person wants her gone – permanently.

With the lives of her family on the line what will Kez be forced to do to save them?

‘Propulsive.’

— Araminta Hall, author of Imperfect Women

Dr Kez Lanyon: Book 3

The Quiet Girls

When MJ Hudson, an old work acquaintance, shows up at Dr Kez Lanyon’s house in the middle of the night, Kez knows she has no choice but to help.

At the prestigious boarding school that MJ’s daughter attends, a teacher has been killed and a pupil is missing. And it seems that the same thing happens every few years. Only this time, the school haven’t been able to cover things up and MJ’s daughter and her group of nice, quiet friends are right at the heart of the scandal.

Undercover as the new school therapist, Kez quickly realises there are some seriously powerful, well-connected forces at play. And by continuing to investigate the mystery, perhaps even stepping outside the law to do so, Kez risks putting her own family in serious danger.

Because no one wants their secrets aired. And some will go to any length to keep them buried.

‘Tantalisingly thrilling, this will keep you perched right on the edge of your seat.’

— Heat magazine

Standalone short

Beach Hut 512

When vandals destroy beach hut 512 on Brighton’s iconic seafront, they reveal a dead body that has apparently lain undisturbed for two months. But according to the hut’s owner, Sims, its locks rusted shut three months ago and she hasn’t had access to it since. So how could the man have got in, and why is there no evidence of the murderer?

Sims has spent the past three years recovering from the trauma of being targeted by a serial killer and narrowly escaping with her life. But this grim discovery feels like too much of a coincidence: could the person who put the body in her hut be the same man who wants her dead? In a desperate race against time, can she uncover the truth behind beach hut 512 before a murderer with a chilling obsession strikes again?

‘Thrilling and twisty with an ending that made me gasp. Highly enjoyable.’

— B A Paris

Dr Kez Lanyon is called onto the case. But can Kez get into Robyn’s mind before she kills again? Or is she about to become Avril’s latest victim?

‘An edge-of-your-seat thriller that’ll keep you guessing right until the end, get this to the top of your reading pile’
