G.R. Halliday was born in Edinburgh and grew up near Stirling in Scotland. He spent his childhood obsessing over the unexplained mysteries his father investigated, which has proved excellent inspiration for From the Shadows. The book was shortlisted for the McIlvanney Debut Prize 2019. G.R. Halliday now lives in the rural Highlands outside of Inverness, where he is able to pursue his favourite pastimes of mountain climbing and swimming in the sea, before returning home to his band of semi-feral cats.
