By day: director of Solicitors for Independent Financial Advice (SIFA).

By night: a genuine crime-busting hero on the mean, ruthless streets of Epsom.

At the ungodly hour of 5.30am one day last summer, Ian Muirhead was cycling his way to work - the Batmobile was in for a service - when he spotted some shenanigans at a bank on the high street of the Surrey market town.

Our man had seen a gang of thieves acting suspiciously - one of them was wearing a stetson.

They were also fitting a micro-camera to a cash machine to film people keying in their pin numbers.

Thanks to the man from SIFA, who pedalled as fast as he could to the nearest police station, the members of the gang were apprehended.

Last week, the criminal mastermind was locked up, so the good people of Surrey can now sleep soundly again.

'It was all in a day's work,' Mr Muirhead says modestly, as he returned to his daytime cover job, dispensing advice on investments and the like.

But we know differently.
