Cat Connolly is back at work. Struggling to adjust to the physical and mental scars, her workload once again becomes personal when her best friend Sarah Jane, daughter of a Pulitzer-winning American journalist, goes missing. Sarah Jane was last seen leaving her workplace - a popular Dublin restaurant - but seems not to have made it home. And then a body turns up, and Cathy fears they have failed to save her friend. But when it transpires that the dead woman is not Sarah Jane, she realises that this case is only just getting started.
