Anisha, an attractive young lady in her thirties, is astounded to find
that someone is sending her a series of diamonds by courier. Her
father, Captain Mehta, had disappeared some years back and the letter
accompanying the diamonds hints at some link between her father and
the diamonds.The diamonds lead the intrepid Anisha, a night club
singer by profession, to the idiosyncratic private detective, Prashant
Saigal and his associate, Dr. Arvind Rao: a criminological expert with
an eye for the beautiful things in life! The trio of Prashant, Arvind
and Anisha reach the house of the man who was sending the diamonds,
namely, the ultra stylish Goutam Dutt. He tells them the intriguing
tale of the Agra treasure, a collection of highly priced jewels that
had its origin some 150 years back and which disappeared nearly 40
years back. The search for the treasure and for the truth behind
Captain Mehta`s death leads the trio to Shillong, to the house built
by Colonel Dutt, the father of Goutam Dutt. The colonel had died in a
strange paroxysm of fear upon seeing a ferocious face at the window.
Saigal and Arvind stumble upon a series of murders including that of
Siddharth Dutt, Goutam Dutt`s brother, mercilessly annihilated by a
poisonous dart - the last in a series of killings that began with the
butchering of the merchant Achmet, at Agra, some forty years ago. It
was Achmet who had been entrusted with the Agra treasure by the
Maharaja of Sitamgarh.Prashant, who has a great liking for single malt
whiskeys, gradually unravels the mystery, aided by his own
hallucinations and dreams. His research, coupled by his own
subconscious, leads him to the mysterious and malevolent Jalaluddin
who is the prime suspect in the Siddharth murder case. In the course
of the adventure, Anisha`s traumas and uncertainties throw her close
to the disarming Arvind, who often has to face the ire of the short
tempered Prashant.Meandering along a path full of strange sulphurous
fires and labyrinthine corridors, Prashant and Arvind engage in a cat
and mouse game with the one legged Jalal. This culminates in an
incredibly complex chase on the Badapani River, a massive water body
surrounded by mountains. The final confrontation between Prashant and
Jalaluddin takes place on the high seas with the mythical treasure
ever remaining cloaked in historical mystery, even as a shaken Anisha
tries to assimilate the nuances of this dream like sojourn.
