Mystery at the Mansion
Iris Blackwood Mystery Adventures · Book 2
Iris Blackwood is twelve years old, keeps her Detective Notepad within arm's reach at all times, and has exactly zero interest in spending her summer sorting through a mansion her family just inherited from a stranger.
She also has a houseful of uninvited guests, a Category 4 hurricane bearing down on Saint Hyde Island, and a locked room underground that hums with gears, clocks, and things that shouldn't be able to move on their own.
Mystery at the Mansion is the second book in the Iris Blackwood Mystery Adventures — interactive detective fiction where you choose what Iris does next. Question the stranger or follow the dog? Trust the eccentric old man or demand answers first? Explore the storm cellar or stay put while the winds build? Every choice leads somewhere different, and not every path leads to the truth.
14 different endings. Four achievement levels, from Desk Agent to Super Sleuth. Three Level 4 endings for readers willing to dig all the way down into the mansion's deepest secrets.
For readers ages 10–13 who want a mystery that rewards curiosity — and the nerve to open the door that hums.
