The Twitchers

Twitch has three pet chickens, four pigeons, swallows nesting in his bedroom and a passion for bird-spotting. On the first day of the summer holidays, he arrives at his secret birdwatching hide to find police everywhere: a convicted robber has broken out of prison and is hiding in Aves Wood. Can Twitch use his talents for bird-spotting to hunt for the dangerous prisoner and find the missing loot?

On a school trip to the Royal Swan Natural History Museum, Ava finds herself at the center of a heist: hundreds of invaluable bird of paradise skins from the Alfred Wallace Collection have been stolen! When she discovers a large jet-black feather, she's sure it's a clue, but the police won't listen to her. Slipping away, she takes the case to the Twitchers in an investigation that leads them to the bizarre and sinister world of fly-fishing, and to a mysterious girl with a pet Raven called Caliban and a dangerous ring of thieves and smugglers.
