The Beltane Massacre by Ray Critch

Rowan McRae is a different kind of hero for a different age, who must learn how to move on after experiencing unthinkable tragedy. A high-stakes mystery and an in-depth exploration of grief and loss, The Beltane Massacre is reminiscent of a classic spy novel—with a modern twist.

Former Canadian Forces intelligence officer Rowan McRae lives in the UK with a beautiful wife and healthy baby. He is about to finish his PhD and assume a teaching post in London, when the unthinkable happens. A bomb is planted in the bonfire at the Edinburgh Beltane Festival, killing many and turning Rowan’s world upside down. One year later, Rowan is enlisted by MI5 to help jumpstart the foundering investigation into the bombing. In so doing, he uncovers a conspiracy touching on the highest levels of society—a conspiracy protecting the bomber.
