Retired agent and veteran polygraph examiner Barry Colvert reviews the over 20 polygraph exams he conducted on the John Walker spy ring case, beginning with Barbara Walker, John's ex-wife who was almost dismissed as a drunken spouse seeking revenge for unpaid child support money and alimony, when she claimed John had been selling military secrets to the Soviet Union. That quirky beginning led to one of the most damaging losses and compromises to national security ever investigated. Barry got confessions from John Walker and his brother Arthur, and interrogated co-conspirators Jerry Whitworth and John's son, Michael Walker.
