Logic) is a 1989 Indian Kannada-language mystery-thriller film,[2] produced by Praveen and directed and written by Sunil Kumar Desai in his directorial debut[3] which is based on Agatha Christie's 1958 play The Unexpected Guest.

[6] The film revolves around an escaped convict who finds the body of a man in his childhood friend's house.

Producers rejected the film due to its unconventional script and complete lack of commercial elements.

[5] Akshay (Shankar Nag), escapes from jail and is being chased by the police when he accidentally runs into the house of Sudha (Vanitha Vasu), a high school classmate of his.

The officer breaks the news to Sudha that the plane by which her husband Kumar traveled to Calcutta, crashed, killing all the passengers.

At present, Akshay disguising as Harish, a friend of Kumar's, meets the mourners and appears to offer support to Sudha.

Sudha receives phone calls from a person who demands a ransom from her husband's property that she inherits following his death, blackmailing her that he would otherwise report the matter of her killing and disposing of Kumar's corpse, to the police.

And, here I was saying my film will have three grey characters, will be shot in a house, without action scenes, songs, hero or villain.

Finally they would ask, ‘will there be at least a little comedy?’ When I said no, they would not invest.”[1] After dropping out of college at the age of 20 Desai went to Bengaluru to enter the film industry.

The major reason of the rejection was due to the parallel cinema tone to the script's subject matter, but finally his close friend Praveen agreed to produce the film.

Desai approached Nag as he had earlier starred in other offbeat films like Minchina Ota (1980) and Accident (1985).

“The sporadic flow of funds caused Tarka to take almost a year-and-a-half to be completed, with dubbing, re-recording and editing.

It ran for 21 weeks in Sapna theatre, Banglore and for 100 days in multiple centers including Mysore, Davngere and Hubli.
