This daddy is a stone cold killer.

You want to know how you give a guy a heart attack? Leave a baby on his doorstep with a note saying: Congrats, you're a daddy.

Not that Declan believes it for a minute. However, until that paternity test proves him right, he's in charge of changing diapers.

Screw that. He's hiring a nanny.

A hot nanny.

A woman who has no idea she's tempting a killer.

Just like those people trying to kidnap his baby have no idea he's not a daddy you should mess with.

But they're about to learn.
