Innocent as Sin by Elizabeth Lowell
Rand McCee just wants to be able to lose himself in his painting. After his twin brother is shot before his eyes while on a scouting mission for St. Kilda Consulting, a Manhattan-based, global business that concentrates on the shadow world where governments can't go. He has finally come to terms with the fact that he will never be able to find the man who shot his twin, the man known as The Siberian. Kayla Shaw is an Arizona banker. Little does she realize that as she has been helping a rich socialite plan how to finance an art exhibition she has been unwittingly caught up in a web of lies and money laundering. When her employer tries to buy her silence, she realizes that she is in way over her head, with no way out. Equally suspicious of and attracted to each other, Rand and Kayla must work together to stop the Siberian before they both wind up in jail - or the grave.
