A firm of accountants was left baffled when a puzzle taxing many of its staff - and scores of business people across Gloucestershire - was found mysteriously solved.

Staff at Randall & Payne reported for work at their Shurdington headquarters this morning and found the solution laid out neatly before them.

But then began another puzzle - just who had solved the perplexing challenge which had so far left staff wanting to know more?

"There were various suggestions made involving staff who are known to work late" said Fiona Hughes, from the firm, explaining how the mystery unfolded.

As you might expect from a firm whose professional integrity and considerable intelligence is built on its eye for detail and ability to interrogate even the most taxing conundrums, it was not long before the identify of those who completed the Punchline charity jigsaw was uncovered.

"There was a fair bit to do," said Fiona, referring to the jigsaw made up of the faces of 247 movers and shakers from the county's business community the firm has unboxed and left in its café area.

"It turns out it was Dani and Courtney from our tax team, who were waiting for a colleague as they were going out after work together.

"The colleague had been delayed after a client visit and had to get something done when she got back late to the office. So they sat in our café area from 5pm to 6.30pm finishing it."

All of which makes Randall & Payne possibly the first business to complete the 500-piece challenge we know of.

Which leaves only one big question - 'have you done your Punchline charity jigsaw yet?'

All funds raised go to Gloucestershire charities the Nelson Trust, The Pied Piper Appeal and Sue Ryder Leckhampton Court Hospice. The jigsaw was made possible by the sponsorship of Randall & Payne, no less, Lister Unified Communications and Tayntons Solicitors.
