Murder Ki Hatya Ka Rahasya - S1.E350

Palash is apprehended by the police for digging up two graves and killing those already dead. When questioned he says his brother Ankit visited him in his dreams and asked Palash to kill them. In the dream his brother is dead. To everyone's surprise Ankit is actually found dead with the same axe Palash talked about. However evidence leads to Terrance Gomes, a CA who was a shareholder in Ankit’s company. Terrance tells KD he didn't kill Ankit. KD finds out that one of the coffins was that of Sam Mendes, Terrance’s Godfather. Both had died in a car crash. Further investigation brings into light the fact that Ankit had accidentally killed them but kept it a secret all along. Now an irrefutable motive is established against Terrance and he is in deeper trouble. Who killed Ankit and Why?
