This book is devoted to the Japanese Noh plays in the fourth group, a colorful assembly of some 90 miscellaneous Noh performed fourth in a formal five-Noh program after the climax of the day's entertainment. While its predecessor (Restless Spirits from Japanese Noh Plays of the Fourth Group) deals with the first four of the nine subgroups into which the fourth-group Noh are divided, Troubled Souls includes six masterpieces chosen from the five remaining subgroups, which deal with fiendish women, mad persons, maskless samurai, street artists, and outcasts.
