Breaking news... Mars Bar found!

Heard from Kathryn, who's one of the Orca dive master trainees: she was helping with a rescue diver course at Capernwray and... well, I'll let her tell the story!
"We found your Mars Bar!!! Well one of the Rescue students surfaced with it looking confused. mucho sniggering. Think he unwrapped it n left it for the fish. Assuming it was one of your rogue chocs, unless there's a copycat out there."

Which leaves two more out there to be found by lucky people (prize: one mars bar). Assuming that it isn't the work of a copycat of course, which is almost too scary a thought to contemplate
