The Mario Mystery: A Dino Moretti (Book 1)

A locked house. A missing boy. Time’s running out.
 
When ten-year-old Mario Rosati vanishes from a locked Tuscan Farmhouse, successful detective Dino Moretti is haunted by memories of the disappearance and murder of his own daughter.
A promise to his wife. His successor newly appointed. This is one case Inspector Dino Moretti must solve. But no one, locals and tourists alike, has seen anything – or they’re just not talking.
When Mario’s father is found dead and a ransom demand arrives, Moretti decides to disobey the orders of his boss and do what he must to find the missing boy.
 
Before it’s too late.
