...is a Soviet-era genre-bending novel by Boris & Arkady Strugatsky, one of their more memorable efforts. A ten-little-indians style mystery with an oddball assortment of characters snowed in at a mountain lodge. Just how oddball is gradually revealed to a by-the-book police inspector.
An Estonian film version, "Hukkunud Alpinisti" hotell, with script by the Strugatskys, showed up on YouTube. Made in the late '70s, yet it looks like an '80s film, with aggressively modern set design, an electronic score, and stylish costuming. Touches of Kubrick and Argento, as much as the budget allowed. The Strugatskys somewhat truncated their plot and characters but the story works, especially the surprisingly emotional ending.
