Also available in audiobook: 

The Twitchers have one last mystery to solve – and this time it’s a heist! The final unputdownable adventure in the bestselling birdwatching detective series from the internationally acclaimed author of Beetle Boy and Adventures on Trains, wildlife queen M.G. Leonard. On a school trip to the Royal Swan Natural History Museum, Ava finds herself at the centre 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… Feather is an exciting winter mystery adventure about friendship, bravery and protecting nature, perfect for readers 9+ and for fans of Robin Stevens, Lauren St John and Jenny Pearson. It can be enjoyed as a stand-alone adventure or read as part of The Twitchers series.
