I haven't yet got a copy of G R Halliday's From the Shadows however I hope to acquire one as its cover reminds me of one of my favourite reads from last year: The Devil's Dice by Roz Watkins.
Here's the blurb for From the Shadows from amazon:
Seven days. Four deaths. One chance to catch a killer.
Sixteen-year-old Robert arrives home late. Without a word to his dad, he goes up to his bedroom. Robert is never seen alive again.
A body is soon found on the coast of the Scottish Highlands. Detective Inspector Monica Kennedy stands by the victim in this starkly beautiful and remote landscape. Instinct tells her the case won’t begin and end with this one death.
Meanwhile, Inverness-based social worker Michael Bach is worried about one of his clients whose last correspondence was a single ambiguous text message; Nichol Morgan has been missing for seven days.
As Monica is faced with catching a murderer who has been meticulously watching and waiting, Michael keeps searching for Nichol, desperate to find him before the killer claims another victim.
