Duty Bound Guardian (Capitol K-9 Unit, 2);

FRAMED 

When a priceless artifact is stolen, museum curator Lana Gomez becomes the prime suspect. How can she hope to adopt her orphaned nephew if she's a person of interest in a crime? Cooperating with Capitol K-9 Unit officer Adam Donovan doesn't get her very far—the handsome cop thinks she's hiding something. But when the real thief returns set on silencing Lana, it is Adam and his Doberman pinscher, Ace, who become her only defense against a madman who wants nothing more than to see Lana eliminated.
