What's wrong, killer got your tongue? It's DC Sean Blake's first week on the job, but already he faces a series of brutal and bizarre killings: women are being strangled in their homes, each with a mobile phone forced down their throat. There are never any signs of a struggle or forced entry. The Greater Manchester Police have no leads. Blake can't afford to waste any time – even as he picks apart the disturbing motive behind the murders, the case takes a turn for the personal. Can he stop the killer before another woman is silenced forever?
