- a charnel smell came from the chest filled with dead men's bones.
-  a grisly murder.
-  ghastly shrieks.
-  ghastly wounds.
-  gruesome evidence of human sacrifice.
-  macabre tales of war and plague in the Middle ages.
-  macabre tortures conceived by madmen.
-  the grim aftermath of the bombing.
-  the grim task of burying the victims.
-  the sepulchral darkness of the catacombs.
