Reviews of Under the Marsh: A Scottish Highlands thriller that will have your heart racing

Deft characterisation, convoluted plot and more red herrings than the North Sea – Under the Marsh is a deft page-turner that doesn't disappoint. * Andrew Greig * An intriguing mystery that brings the Scottish highlands and those who live there vividly to life. I loved it. * Marion Todd * Chilling and breathtaking all at once, Under the Marsh grabs you by the throat from the off and it never lets you go. Stellar writing and GR Halliday's best yet. * Jonathan Whitelaw * Loved it. A fabulously atmospheric read. Thoroughly enjoyed the past and present strands that kept me guessing throughout. So cleverly done. There were many ways it could've gone but, the way it did, was such a satisfying end. * Deborah Masson * G.R. Halliday has created a wonderfully atmospheric and taut novel with UNDER THE MARSH. Perfectly paced and deliciously misleading, I was led down various different rabbit holes to find out what had happened, and to keep this level of intrigue is something so difficult now in this genre! Hugest congratulations. * L.V. Matthews *
