Hollow man novel

"Only two other people know that Dominic, a charming Englishman, prosecutor, and musician in Austin, Texas, is also a psychopath. They also know that a year ago he got away with murder. One of those people is his "special lady," and the other is her brother, a teenager and fellow psychopath called Bobby. When a wily homicide detective starts digging up that past murder, little Bobby offers to take care of the problem--permanently. Dominic tries to dissuade him, but as he himself knows, psychopaths aren't good with following instructions. Or impulse control. As Detective Megan Ledsome circles closer, Dominic knows his life depends on keeping his secrets hidden, from her and the rest of the world. And when his annoying office-mate declares his interest in a judicial position, one he himself would like, Dominic realizes that one of his carefully-orchestrated plans could kill two birds with one stone. Of course, that means some sleight of hand and a sacrifice or two. But if there's one thing a psychopath doesn't mind, it's sacrificing other people"--

"A Texas prosecutor with a lot to hide forms a conspiracy with two confidants to keep a snooping detective away from discovering the truth, even though the plot may involve murder"--
