Detectives investigating the murder of Wisbech pensioner Una Crown, 86, say they have received an encouraging response from an anniversary appeal.
Mrs Crown's body was found in her bungalow three months ago. She had been stabbed and her body set on fire.
Letters appealing for information were posted to every household in Magazine Lane last week and a mobile police station set up nearby.
Posters went up advertising a £10,000 Crimestoppers reward . The police say they are following up a number of fresh lines of enquiry.
