Fifty nine years ago today, Alice and Norman Thomson got married. But the symbol of that marriage - an engraved wedding ring - was stolen in a burglary thirty years ago. It was found by Debbie Davidson, who unearthed it when digging out a pot plant from her Edinburgh garden. Debbie sent a message to her old school friend, Martha Kearney, who turned to Twitter to help. She posted Debbie’s message with the hashtag #FindAliceandNorman and after more than two thousand retweets, a citizen army helped track down Alice Thomson, who lives just round the corner from Debbie. Norman died in 2013. Here is the moment Alice was reunited with her wedding ring after 30 years. Credit: Debbie Davidson
