Alan Murphy and the Hidden Icon

When Alan Murphy and Brent Blakely notice a slight nod from an elderly lady to an elderly gentleman, they become suspicious. Before that nod, the two had not appeared to get along at all. Their detecting gets them in trouble and drugged by a remote-controlled mosquito device. With the help of Lynette Roberts, a thirteen-year old and Brent's mother, they manage to gather enough evidence to alert the authorities and thwart a 4-billion dollar robbery.
