Thanks to journalist Michael Havis for writing up and circulating the story to the national press.  Read the article here.

Journalist Mathilde Frot, author of yesterday's article in Jewish News, has been in touch with Parcelforce, to see if the newspaper's interest might provoke another search.

Parcelforce have responded today to confirm that they cannot locate the package.  They have said they would like to provide us with a "goodwill gesture" and donate money to a Holocaust memorial charity of our choice, so we will follow that up with them.

However, it is disappointing news, and we're still hoping for a miracle.  If anyone has ideas with regards to the journey a stolen item of this sort (i.e. gold) might take, to help us redirect our search, so let me know.
