14. Never Trust A Ghost.
Marty leads Jeff astray as he gets Jeff to tell the police of a murder. Unfortunately the murder victim isn't dead, a mistake by Marty. This happens a few times involving the same guy, Howarth, and when Jeff discovers Howarth is the guy in charge of the payroll at MI6 then the case takes on a different look.
Is Howarth really dead or not, is it an imposter in his place. With Howarth fed up with Jeff's continual harassment the police are called and in a great scene Jeff uses Jeannie as an alibi , by getting into bed with her as the police come calling. Marty though accompanies the police and sees Jeff with his widowed wife and goes spare.
