Scottish essayist, novelist, and poet. Well-known for his adventure stories Kidnapped and Treasure Island, as well as for the startling tale of Dr. Jekyll and Mr. Hyde. ALS, one page of lightly lined graph paper, 4.5 x 7, no date. Letter to Mrs. Ehrich. In full, “I am in bed and in the least gallant and the least grateful frame of mind conceivable. A little essay on the the relation between civility and temperature were needful to defend my silence. And truly I do not feel able to write anything but the merest note. All I can say (and indeed I scarce know if it be an excuse or an aggravation) is this; though I have never written to thank you, I have been finishing your cakes. I shall hope someday, when I get rid of my enemy, to thank you in person both for the cakes and the note that came with them.” In fine condition, with expected mailing folds, ligth toning, and a small stain to left edge. COA John Reznikoff/PSA/DNA and R&R COA.
