A particularly agile, athletic and elusive thief.
Named after so called "Spring-heel Jack" a notorious pickpocket and burglar, active in Manchester(England) in the 1950's
Jack(Spring-heel)McMaster was finally caught in 1959 after committing an estimated 900+ offences. Though he never used violence,being too fast to be caught,he was sentenced to 8 years in gaol. He escaped from Strangeways gaol after 3 days and was never apprehended again.
It's generally safe in Barcelona, but you've got to watch out for spring-heels.
Be careful ...watch out for spring-heels !!
He's OK, but he's a bit of a spring-heel Jack (said as a term of endearment)
