With darkness approaching, Tom Darling attempts to wrangle one of the biggest brown trout of his life to the boat. IFI’s Shane O’Reilly waits patiently with the net. The fish had been heading toward his fly, hoovering up naturals as it went, before it veered off and took Tom’s small mayfly imitation. Once hooked, it bored down deep; Tom could feel the leader moving over its back. Darkness had fallen before Shane finally drew the net underneath it. Photo: Ben Etridge
