A case that twists and turns…

When Dr Romilly Cole learns of the murders, they trigger memories of a traumatic past she has tried hard to forget. But getting involved with the case is a bad idea. She and Bishop have history – and working together could never end well.

A race against time to stop a killer…

‘Fierce, frightening, twisted and addictive. The Twenty grips you by the throat and keeps on squeezing until the very end’

‘If you like crime that’s dark, twisted, and keeps you up all night, Holland is the author for you’
