He dressed as phone repairman and watched the blackmailer take the plastic bag Gail had left for him in a phone box. Suggested answer : Lenny did not tell the police about the blackmailer because it was his friend and former work colleague Rik. I could understand why Lenny would not want to tell the police that his Friend was the blackmailer and send him to jail. Lenny was able to return the money and photos to Gail. The case was solved , so there was no reason to tell the police about Rik's involvement.
