Red Nails is the last of the stories about Conan the Cimmerian written by American author Robert E. Howard. A novella, it was originally serialized in Weird Tales magazine from July to October 1936. It is set in the pseudohistorical Hyborian Age and concerns Conan encountering a lost city in which the degenerate inhabitants are proactively resigned to their own destruction. Due to its grim themes of decay and death, the story is considered a classic of Conan lore and is often cited by Howard scholars as one of his best tales.

Co może się wydarzyć, gdy szalona dziewczyna pozna zamożnego introwertyka? Absolutnie... wszystko. Róża za dnia jest zwyczajną kobietą, za to nocą zmienia się w czerwonowłosą didżejkę, która porusza tłumy na parkietach. Najbardziej w życiu ceni muzykę. Sama ją tworzy i z nią wiąże swoją przyszłość. Feliks to bogaty, zamknięty w sobie facet. Pracuje w wytwórni muzycznej ojca, ale marzy o innej karierze. Niestety rodzinne zobowiązania czasem okazują się ważniejsze niż nasze pragnienia. Mówią, że okazja czyni złodzieja, a Róża oprócz muzyki kocha szybkie, sportowe samochody i lubi czuć adrenalinę, więc gdy widzi granatowego mustanga, działa natychmiast. Nie podejrzewa tylko, że w "pożyczonym" aucie będzie drzemał... Feliks. Czy ta przypadkowa znajomość przerodzi się w coś więcej?

The moonlight shimmered hazily, making silvery mists of illusion among the shadowy trees. A faint breeze whispered down the valley, bearing a shadow that was not of the moon-mist. A faint scent of smoke was apparent. The man whose long, swinging strides, unhurried yet unswerving, had carried him for many a mile since sunrise, stopped suddenly. A movement in the trees had caught his attention, and he moved silently toward the shadows, a hand resting lightly on the hilt of his long, slim rapier.
