In the Dark (Впотьмах, Vpot'makh) is a short novel by Alexander Kuprin originally published in Russkoye Bogatstvo magazine's June and July, 1893, issues. Later the author drastically edited this first version, and in this cut form it appeared in Rodina magazine, 1912, Nos. 32-34, 36-40. Written in the years of Kuprin's military service, In the Dark is considered to be his most important work of that early period.
