Azarov followed him to the corner by the door to something covered with a gray oilcloth. It was full of angular bumps, and yellow, bony toes stuck out from the ends.

Life had not often placed Arkady Arkadievich face to face with death. He felt faint and unbuttoned his collar. The raised oilcloth revealed sticky, short hair, bulging eyes, sunken cheeks, a mouth drooping at the corners, then a prominent Adam's apple on a sinewy neck, thin collarbones…. “He's lost so much weight!” he thought. “Yes.”

Harry Haritonovich was considered attractive: a good physique in a light suit, a well — shaped head, intriguing gray at the temples, dark eyes, and a good straight nose, set off by a dark mustache.
