John Gray served as an Edinburgh policeman for several years in the mid-19th century and, like other officers on the beat at the time, he has had to provide his own police dog: the faithful Skye terrier that came to be known as Greyfriars Bobby. With petty thieves at work in the high street and a gang of ruthless house breakers at work in both the Old and New Town area of the city, the new recruits have their work cut out.
