The Word of a Child: 3 Good Cops (Harlequin Superromance No. 1009)

On an ordinary day, in an ordinary neighborhood, a knock on the door of an ordinary house leads to an extraordinary revelation. Detective Connor McLean is the man who came to call, carrying with him a child's accusation. Connor's visit ended Mariah Stavig's marriage and left her a struggling single mother. Three years later, the word of another child brings Connor back into Mariah's life. Connor knows his investigations can ruin as much as they fix, but he has no choice. He has sworn to speak for the innocent and seek justice for the victims. And now, to do his job, he has to have Mariah's help -- no matter how much she hates him.
