Is it violence if it's virtual? The outspoken women targeted by the increasingly cruel internet trolls and bullies would probably say so. For some of them, the torrents of bile and vicious threats prove too much. They begin to silence themselves in a series of high-profile suicides.

Unpredictable and un-put-down-able, Splinter the Silence is a must-read that cements Val McDermid's place as one of the best crime writers in the business.
