Be My Little Baby - London Detective Agency, #2

When Tessa Lopez opened her bakery, she expected to barely break even. Instead, she's become one of the most popular shops in London. Life would be perfect, except someone is stalking her, sending 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 uncover her stalker, Tessa and James fight an undeniable attraction.
But he doesn't date clients, or so he keeps repeating. Will they be able to resist their attraction and survive the person hellbent on making her his, at any cost. Or will their chemistry bring about their end? Tropes: damsel in distress, protector, private investigator, forbidden love, beta, international
