It was the phone call from a police detective that told Tricia Griffith she had been right all along. In 2008, and in her late-40s, she had given up a 25-year career in radio to work full-time on websleuths.com, an online forum whose members band together from all over the world to investigate unsolved crimes.

The call she took from the detective was about Abraham Shakespeare, a casual labourer who'd won $30m on the Florida lottery in 2006, before going missing in 2009. Not long after his disappearance, Websleuth members began discussing the case, and many became suspicious of Shakespeare's business partner, Dorice Dee Dee" Moore, who had come into possession of Shakespeare's wealth and assets.
