TLS, one page, 5.5 x 7, Winterbrook House letterhead, January 17, 1969. Christie writes to Debbie Steinberg in Philadelphia. In full: “I receive a great many fan mails saying nice things about my books. I do not usually pay very much attention to them, I am afraid, but I would like you to know that your letter arrived at a moment when I had been through my own period of painful and prolonged depression over an illness of my own and of my husband’s, and also the loss of an old friend. It cheered me very greatly to get your letter of gratitude and to know that I had been a help to you in a sad period of your own life….” Accompanied by the original mailing envelope. In fine condition. R&R COA.
