A novel by Frank Simon
Eric Mason and Gary Nesbitt, leaders of SecurityCheck, Inc., have earned the job of a lifetime--testing the defenses of the Tower of London. The two Christians are hired to attempt a break-in to steal the Queen Mother's crown and see how well current security systems are working. With the help of computer expert Ann O'Brien, a new believer with a checkered past, they succeed in their mission--only to find themselves conned out of the priceless artifact. Now the team must steal back the crown or face long years in jail for pulling off the biggest heist in Britain's history.
