Closure of a Local Bookshop
Book-lovers will be sad to hear that the owners of Morton’s, the well-known high street bookshop, have announced its closure. The family-owned bookshop has been selling its wares in the town for more than 50 years and it will be sorely missed.
Mr. Robert Morton said last night, “We are having to close because of financial circumstances. It is Hobson’s choice. We have fought tooth and nail to keep the shop open, but our efforts have been unsuccessful. Now we have decided that enough is enough.
