Moscow

Tall, with a bluish-white very thin face, dressed in a long black hoodie, moves silently. It usually appears in wet, warm weather when it rains. Birds do not fly away when a "monk" appears, and dogs do not bark at him. 

It appears on the eve of great misfortunes. It was noticed, for example, in August 2000, the day before the explosion in the underpass on Pushkin Square. You can't call him and talk to him.
