Burrowes, Grace. Lord Julian mysteries #3

"Lord Julian Caldicott, still recovering from his years at war, is tasked with investigating the circumstances of a small boy who could be either the salvation of the Waltham dukedom or a pawn in a scheme to sink the Caldicott family in endless scandal. The boy is alone in the world, though any one fo several women might be his mother, and they all claim that Julian's brother, the late Lord Harry Caldicott, was the child's father. To uncover the boy's parentage, Julian must face demons from his own past, solve puzzles left behind by Lord Harry, and thwart enemies who wish the lad harm fro reasons of their own.

The longer he searches, the more tangled-and dangerous-the mystery becomes, for Julian and for the innocent child who deserves to know the truth of his own birthright" -- Page [4] of cover
