Undercover Passion (Undercover Justice, Book 3) (Mills & Boon Heroes)

He’s not who he says he is. But he’s her only hope.

Undercover detective Harley Maxwell has spent years tracking a master criminal. And the key to capturing his archrival lies with single mom Liz James, who might be aiding his target. Making Liz talk—by getting close to her—could also unravel a connected mystery that’s haunted Harley for years.

But when her young daughter is kidnapped, getting the girl back becomes all that matters.
