Nearly five decades ago, a popular Tamil weekly published a serial called THUPPARIYUM SAMBU (Sleuthing Sambu) written by Devan, a humorist comparable to P.G.Wodehouse in creating immortal comic characters. This was an instant success because the hero, Sambu was a uniquely entertaining "sleuth" who established rapport with the entire Tamil reading public with his "exploits" which unearthed many peculiar crimes which were "solved" mostly by accident when Sambu stumbled on the clues.
Sambu's friend, Venkittu, who had promised to encourage Sambu in his new career by bringing him cases, sends Singaram, ICS to Sambu. A confident Sambu who is excited about his first case, is nervous and frightened by the presence of a police Inspector. How Sambu identifies the culprit thereby sealing a friendship with Inspector Gopalan is what this episode is about.
