Mystery At Ebenezer Lodge by Dunni Olatunde

The Ilesanmi children are on holidays at their grandparents’ house in Ibadan, until their grandfather has to travel to Ilorin urgently. Along with their neighbour, Nosa, they are sent to spend one week in the care of their grandmother’s aunt, 79-year-old Mama Onireke of Ebenezer Lodge.

But the old mansion holds more in store for them than a quiet holiday. Someone is getting into the old buildings on the grounds without using the doors. The children are determined to get to the root of the mystery at all costs.
