Gangtokey Gondogol (Trouble in Gangtok) is a short novel by Satyajit Ray featuring the private detective Feluda.

[1] Feluda and Topshe travel to Gangtok for their summer holidays at the start of the Bengali new year.

While eating breakfast at the Bagdogra Airport, they meet a man named Sasadhar Bose, who works for a chemical firm dealing with aromatic perfumes.

While stopping at a place called Teesta Bazaar, the duo learn of an accident which occurred on the North Sikkim Highway; a taxi had fallen off a cliff, after being hit by a huge boulder, with the driver managing to escape, unhurt.

In the evening, Bose comes to Feluda's hotel and informs him that the man who fell down the cliff in the accident, was his partner Shivkumar Shelvankar, who was also the owner of the company.

Helmut tells Feluda that on the day of the accident, Shelvankar and he had decided to travel to a gumpa on the way to Singik.

He reveals to Feluda that Shelvankar used to keep the statue with him in his breast pocket as he considered it to be a lucky charm.

Feluda asks the driver of the taxi he is travelling in, to come in the morning the next day because he wants to see the scene of the accident.

Later Nishikanto tells Feluda that there is a lama dance the next day at Rumtek and they decide to go and see it in the afternoon.

Nishikanto, Helmut, Feluda and Topshe travel to Rumtek for seeing the lama dance later that day.

Feluda learns, through a telegram, that Shelvankar's estranged son is present in a Sikkim monastery and a detective agency has found him.

Dr. Vaidya, who specializes in talking to souls of the departed, tells all of them (through Shelvankar's spirit) that he was murdered and Virendra is responsible for it.

Feluda tells Topshe that today he will conduct an experiment on the North Sikkim Highway.

After conducting the experiment, Feluda concludes that the murder was done by first hitting Shelvankar with a rod and then throwing the vehicle down the cliff.

It shows a man wearing red clothes standing on top of the mountain and seeing the car falling down.
