realise that the police have failed to apprehend him yet again. Marty hears this and gets back to Jeff who is, at that time, driving back to his office. Marty tries to convince Jeff of this plot but Jeff is dismissive after his visit to Plevitt. Jeff placates Marty however by suggesting that he checks the office out first before he goes up there. Whilst Marty is doing this Jeff is shot at by Rawlins in a waiting car. The bullets put holes in Jeff's windscreen and narrowly miss him. Jeff's faith in Marty is once again restored and he returns to his office. Shortly after this Jeff is visited by Rawlins, masquerading as a potential client. However Marty recognises him and advises Jeff, whereupon a fight ensues. Unfortunately Jeff comes second in this encounter and is taken, unconscious, back to the Howarth house and is tied up. The plan is for the spies to leave that night for the airport and leave the real Mr & Mrs Howarth's bodies in the living room with Jeff, who they plan to also shoot and make it look like he killed the Howarths and then shot himself. At this time the imposters reveal that they are spies for a foreign (undisclosed) country and that they chose Mr Howarth to impersonate as he is in charge of salaries for various British Intelligence agencies and, as such, he has access to every undercover agent's details used by the UK. The imposter Howarth has been busy photographing all the important documents whilst he has had access to his place of employment. Marty pays Jeff a visit before the spies have had a chance to murder him and Jeff advises him to see Plevitt and convince him to call Scotland Yard and say that a murder is about to take place at the Howarth's address. Plevitt can see Marty but assumes that he is not telling him the truth. He insists that Marty takes some tests before he'll be convinced by the truth of what he's saying. Marty passes with flying colours of course and Plevitt eventually decides to call the police. They arrive in the nick of time just as the spies were planning on shooting Jeff and Jeff is finally able to give a first hand account of what's been going on to Inspector Clayton and the spies are arrested.
