The letter concerns the value of the contents of Plas Penrhyn. Edith believes most of the books have been insured by McMaster University, but are they? She thinks the Epstein bust has been insured separately. Her personal assets are worth £13,000 and the Estate's £2,000. Also in the file is a handwritten, very detailed working sheet, document 313586A, listing each room and its contents and values. There are 19 rooms in all including the halls.
