A chat with a museum curator at England’s secret wartime decoding centre has led to a Hook grandmother writing her memories in a new book.

Muriel Davison, 89, was a radio mechanic at Scarborough’s secret listening station in the Second World War.

She serviced the valve radios which picked up signals from German U-boats and warships in the North Sea after signing up with the WRNS.

The intercepted messages were then taken by motorcycle courier to Bletchley Park, where they were decoded by genius early computer experts.

One piece of equipment was the famous Enigma machine.

Mrs Davison said staff at Bletchley Park Museum had inspired her.

She said: “They were really encouraging and wanted me to write down everything. I was able to recall everything vividly, so got it all down and then it was suggested by my family that it would make an interesting book.”

Mrs Davison is an active member of the Kingston on Thames WRENS Association. She was living in Villiers Avenue, Surbiton, when she went off to serve in the war.

The 56-page book is packed with 50 black and white photographs.

The book, “A Wren’s Tale – The Secret Link to Bletchley Park,” costs £5.95 and is available from Chessington Garden Centre, the Regency Bookshop, Surbiton, or by calling 01737 221215 to get a copy in the post.
