Be My Little Baby (London Detective Agency Series) by Stephanie R. Caffrey

When Tessa Lopez opened her bakery, she expected to barely break even. Instead, she’s become one of the most popular shops in London. Someone is stalking her, though, sending her threatening letters and photographs. When the police can’t help, she goes to the famous and too-sexy private detective, James Moore. As they work to solve who her stalker is, Tessa and James have an undeniable attraction. But he doesn’t date clients, or so he keeps repeating. As the stalker grows bolder, will they be able to resist their attraction? Or survive the person hellbent on making her his, at any cost.

Tropes: damsel in distress, protector, private investigator, forbidden love, alpha, international
