Penny talks to Richard and Judy about her novel ‘Tideline’

“He comes to me when the chatter of school children has died away.

There is a silent time, almost as if the river and I are waiting.”

On a winter’s afternoon, Sonia open the door of her beautiful Greenwich home to fifteen-year-old Jez, the nephew of a family friend. He’s come to borrow some music. Sonia invites him in, pours him a drink – and realises she can never let him leave.

Haunted by memories of an intense past relationship, Sonia is filled with an overpowering desire to keep Jez hidden and protected from the outside world. It is as though her own life depends on it. And outside, on the shores of the Thames, long held secrets are coming in on the tide.

A dark and evocative thriller...

S. J. Watson (author of ‘Before I Go To Sleep’)

Brilliant and totally gripping. It's such a thrill to read a book as deliciously dark and richly evocative as Tideline. From the first page to its shocking finale it draws you into its world and won't let go.
