Publisher's Synopsis
In this 10th book in the Key Mystery Series, Nick, Mandy and friends are excited to be staying at an ancient castle in Scotland. After hearing about the legendary Sinclair treasure, guarded by a mysterious White Lady, the children set out on a quest to find it. Someone, though, is desperate to stop them. Is it the ghost of the Black Knight, killed in battle in 1302, and still roaming the glen on his horse? Or his fierce war hound they hear howling on stormy nights? Or could it be the creepy old man they see prowling the grounds with a shovel? After an intruder breaks into the castle, the mystery ramps up and the children are in a race against unknown forces. Will they find the key to the treasure in time? The Black Knight's Key, a suspenseful tale of graves and ghosts, danger and determination, will keep 8-12 year olds reading to the spellbinding conclusion.
