Anil Ganguly, a very good director who repertoire comprises of some wonderful classics such as Kora Kagaz, Tapasya, and some entertaining films such as Trishna, directs an unusual Hindi film - a murder mystery the title of which pretty much sums up the story, who and how. The detective in this film is none other than the star of the day, Mithun Chakraborty, who does wonderfully in a restrained act.
Anything that's shot in Shimla like this one is worth the watch for me, especially in snowy winters. The views and the landscapes serve a wonderful backdrop for the story. So do the sets, the classical design of which makes for cozy, authentic homes well suited for the kind of suspense we have here. Even the action is minimal, and the film is relatively short. A lesser known film but definitely worth a watch.
