At eighty-three, Isabelle has earned the right to make her own decisions.
Her family is less certain.
When Isabelle calmly announces that she has met a man - and intends to marry him - Mara and Luca's famously inquisitive family reacts exactly as she expects: with affection, alarm and an almost immediate investigation.
Alexander Foster is seventy-nine, widowed, retired and disarmingly decent. He makes Isabelle laugh. He treats her as an equal. And, inconveniently for the suspicious Bellinis, almost everything they discover about him appears reassuring.
Almost.
There are unexplained gaps in Alexander's past. Private phone calls he refuses to discuss. Questions about wills and finances that sound sensible - until they don't. And somewhere behind his quiet retirement is a story he has never told Isabelle.
Mara wants to protect her mother. Luca is determined not to let a charming stranger take advantage of someone he loves. Sofia follows the gaps in Alexander's history. Matteo searches for the digital trail. But Isabelle has a question of her own:
When does protecting an older person become taking away their right to choose?
As the family's suspicions lead them toward a very different kind of danger, they discover that the gentleman in question may not be the threat at all. He may be one of the few people who has already recognised it.
Warm, funny and quietly suspenseful, The Gentleman in Question is a contemporary family mystery about love later in life, financial exploitation, grief, independence and the difficult line between caring for someone and controlling them.
Because growing older does not mean surrendering the right to fall in love, take risks, make mistakes - or decide for yourself whom to trust.
