Ex-SAS 'surveillance expert' Dave Thomas

Clare chats to ex-SAS man turned 'surveillance expert' Dave Thomas about his life as a spy.

At one stage Dave was the youngest person to make it into the SAS. When he left he began a career as a spy, overturning corperate fraud and tailing terrorists.

Nowadays Dave runs a company organising team building events and parties that give normal people the chance to learn 'spy skills'.
