The Secret Detectives Mysteries Series

by
(24 reviews)

Drawing inspiration from the golden age of cosy crime and The Secret Garden, we believe this gripping historical mystery series will make all children aged 7+ fall in love with reading. 

The books follow a young Isobel Petty, who has been taken away from her home in India to live with a distant uncle in England, and on her journey becomes witness to a murder. As expected, no one would ever believe a child, and so she takes matters into her own hands with two new reluctant friends, hoping to find the answers she seeks before reaching England.

This is a story of new beginnings, finding friends in the darkest of times and facing our fears. We recommend this to all fans of Robin Stevens and Katherine Rundell.
