Lets have a look thru the keyhole and see what comes up.
A female employee of Essex-based publisher PSI Ltd., Loughton, who just happens to be an avid Jeremy Bamber supporter offers to provide author Paul Harrison access to a database of over 100,000 email addresses including potentially sensitive contacts within the Home Office and other government departments. This was undoubtedly done on the basis that these contacts might have been useful to him as he was writing a book which challenged Jeremy Bamber's conviction.
However, this all changed when Harrison, having investigated the case in some detail, came to realise that Bamber's conviction is in fact sound. Somebody must have been really pissed at this having put her job on the line to help Harrison.
Last month Harrison received a letter at his remote home on the Orkney Island of Sanday in which several threats were made against him if he harmed Bambers chances of getting out of prison. The letter was posted in Essex.
Harrison's postal address on the island of Sanday would not be in the public domain but someone who worked for a publishing Company could very well have access to this information as Harrison has been an author for several years. Thus we have closed the circle, a disgruntled employee with a score to settle who just happens to have access to a database of names and addresses. Moreover, an employee who lives within a short commuting distance of Loughton.
Only one person fits in this particular house of cards!
