Magnum, P.I.
Don't Say Goodbye
S1 E15:
Having once been hired by wealthy, blind Agatha Kimball to find her missing granddaughter Amy, Magnum's services are once again called upon by his elderly friend after she has been contacted by a blackmailer claiming to have some important information about Amy. She instructs Magnum to pay the man and get rid of whatever the information about Amy is without investigating further, but when Agatha is nearly killed in a series of suspicious accidents, and when the blackmailer is shot dead during the delivery of the ransom, Magnum decides he must ignore instructions and investigate just what trouble his elderly friend and her granddaughter are in.
