"Simply Lies" is the fourth David Baldacci book I have read in the past year -- and there is a lot to like in this psychological thriller.  Mickey Gibson, single mom and former Jersey cop is now juggling the demands of her two small children as she works remotely for a global investigation company that hunts down wealthy tax and credit cheats.  When Mickey gets a call from a colleague named Arlene Robinson, she thinks nothing of Arlene’s unusual request to go inventory the vacant home of an arms dealer who cheated ProEye’s clients and fled. That is, until she arrives at the mansion to discover a dead body in a secret room—and that nothing is as it seems. On top of that, there is no Arlene Robinson -- and the victim in the house is a former mob informant.
