The Mystery of Holly Lane (Five Find-Outers #11)

With nothing to find out, the children decide to get in a little practise and one task set for Larry was to disguise himself as a window cleaner and go to clean someone's windows. So Larry cleans the windows of a bungalow on Holly Lane, where an elderly man lives, not realizing that this very bungalow and the elderly man will soon turn into a mystery for the Find-Outers, which involves money gone missing, and the sudden disappearance of the elderly man's grand-daughter, Marian. With only a handful of clues to help them, such as – a window cleaner, grocer's boy, lady with papers and a man in a car – the Find-Outers are really challenged with this mystery.
