S1·E297 Darr @ The Mall: Part 2

Strange incidents take place at the Manglam shopping mall, every 'no moon' night. The night security guard finds a ghastly apparition, floating through the mall galleries, and then witnesses the ghost murdering the owner. K.D Phatak's friend visits him saying an employee from his agency has been arrested. K.D Phatak takes up the case and starts the investigation. Was it really the ghost that murdered the owner, or is it a plot to the case?
