The name may have been changed to Harper to capitalize on Paul Newman's recent success with HUD (1963), but this private-eye mystery is unmistakably based on a Ross MacDonald Lew Archer novel. When a millionaire businessman turns up missing, his estranged invalid wife (Lauren Bacall) hires private detective Harper (Newman) to find him. The P.I. quickly discovers that the victim has been kidnapped by some of those nearest and dearest to him, and uncovers a tangled web of smuggling, greed, drugs and petty family jealousies. With a script from prolific longtime Hollywood screenwriter William Goldman, this Lew Harper detective thriller was followed up nine years later with the THE DEAD POOL (1975).
