An officer of Barrackpore Police Commissionerate, under which the area falls, said the charred body of Pratima Kundu (52) was found in the gutted mattress of the bed room while Pratima's 53-year old husband was found lying with extensive burn injuries on the door step of the room as fire services personnel entered the premises after dousing the flames.
The man was admitted to R G Kar Medical College and Hospital.
Two fire tenders put off the blaze which was suspected to have been caused by short circuit.
