A Danish fisherman is desperate to solve the mystery of a message in a bottle found in a fjord north west of Copenhagen.

Niels Gade, now 71 found the scribe on an August day four years ago.

But when he retrieved a message from the glass vessel he didn’t find an SOS message or a love letter - but a puzzle which he has never been able to solve.

The single piece of paper found inside featured only a name and an address - supposedly in Cardiff .

Puzzling address

The name was James Christopher and the address 25 St Pauls Street Cardiff.

The bottle may well have travelled for more than 692 miles from the Welsh capital to end up lapping against the side of a Danish fishing boat in the town of Frederiksværk.

But the mystery has deepened further as there is no St Pauls Street in Cardiff.

The fisherman, Niels Gade, sent a letter to the address written inside, asking a series of pressing questions such as when was the bottle sent.

But, the Royal Mail returned Niels attempt at making contact without stating why.

Perplexed and with no other avenues to explore, Niels forgot he even had the bottle, until recently finding it again hidden in the back of a cupboard.

'Mysterious story'

As a result he decided to have one last go trying to locate the author of the note, by contacting Danish Newspaper Halsnæs and asking them to run the story.

Editor of Halsnæs Anders Nordstrand said: “This message and this bottle have travelled many nautical miles.

“Niels thought it might have been a sailor who just wanted to send a message.

“It’s just a very mysterious story, like the beginning of a film.”

Anders is equally baffled by the mystery and hopes that the truth will come out.
