After a distinguished career in the police force, it wasn't as if DI Kate Redman was expecting maternity leave with newborn twins to be a breeze exactly. However....

When local woman Carrie Rawlins disappears without a trace, Kate's friend DCI Mark Olbeck pleads for her assistance. Despite being knee-deep in nappies and struggling with sleepless nights, Kate quickly realises that Carrie's troubled personal life might be the key to unlocking the mystery.

Carrie's husband, Russell, had been at the epicentre of a medical scandal that rocked a far-flung maternity unit. Rumours of negligence, cover-ups, and unethical practices had left a trail of shattered trust and broken lives in their wake. But is the couple's murky past really the reason behind Carrie's disappearance?

Undertow is the sixteenth novel in the USA Today bestselling series The Kate Redman Mysteries, by author Celina Grace.
