Tammy Cohen’s latest psychological thriller, When She Was Bad, is published on Thursday 21st April, and is already receiving rave reviews. Good Housekeeping made it their Thriller of the Month in April and The Literary Review described it as ‘intelligent and satisfying’, while CL Taylor said ‘psychological thrillers don’t get much better than this.’

The characters in When She Was Bad have worked together for years – they know how each one likes their coffee, whose love life is a mess, whose children keep them up at night. But their comfortable routine is shattered when an aggressive new boss walks in. Now, there’s something chilling in the air. Who secretly hates everyone? Who is tortured by their past?

Who is capable of murder?
