Blood Knots. Of Fathers, Friendship and Fishing; Atlantic, 2011

As a child in the 1960s, Luke Jennings was fascinated by the rivers and lakes around his Sussex home. Beneath their surfaces, it seemed to him, waited alien and mysterious worlds. With library books as his guide, he applied himself to the task of learning to fish.

His progress was slow, and for years he caught nothing. But then a series of teachers presented themselves, including an inspirational young intelligence officer, from whom he learnt stealth, deception and the art of the dry fly. So began an enlightening but often dark-shadowed journey of discovery. It would lead to bright streams and wild country, but would end with his mentor’s capture, torture and execution by the IRA.

Blood Knots is about angling, about great fish caught and lost, but it is also about friendship, honour and coming of age. As an adult Jennings has sought out lost and secretive waterways, probing waters ‘as deep as England’ at dead of night in search of giant pike. The quest, as always, is for more than the living quarry. For only by searching far beneath the surface, Jennings suggests in this most moving and thought-provoking of memoirs, can you connect with your own deep history.
