Saxby Smart is a schoolboy detective. He may have to be home in time for dinner, but his genius is never off the case. Here, Saxby pits his wits against adversaries old and new: his arch nemesis - who's plotting an ultimate revenge, thieves who make a truckload of video games vanish into thin air, and whoever's behind the apparently pointless robbery of the school office! Packed with mind-mangling mysteries and fizzing with humour, three new case files are opened for the reader to join Saxby's adventures, and solve the cases themselves!
