Thicker Than Water

Thicker Than Water is a compelling murder mystery set in northern Scotland.

Callum Anderson and Jenny Mackay are spending Hogmanay at Sarclet Castle in Caithness when they are asked to investigate the brutal murder of a young woman at nearby Sarclet Broch in 1943, a woman whose ghost is believed to haunt the castle.

What seems the coldest of cold cases is not the first murder of a young woman at the broch: there was another nearly two thousand years earlier. Nor is it the last. On the day that Callum and Jenny arrive, there is a third fatal stabbing there.

Their investigation into the 1943 murder uncovers shoddy police work and the possibility of a serial killer: but can anything be proved after eight decades? Meanwhile they find themselves drawn into the increasingly dangerous hunt for the latest murderer.
