Many of the stories collected here are pure Jansson, touching on island solitude and the dangerous pull of the artistic impulse: in “The Squirrel” the equanimity of the only inhabitant of a remote island is thrown by a visitor, in “The Summer Child” an unlovable boy is marooned along with his lively host family, in “The Cartoonist” an artist takes over a comic strip that has run for decades, and in “The Doll’s House” a man’s hobby threatens to overwhelm his life. Others explore unexpected territory: “Shopping” has a post-apocalyptic setting, “The Locomotive” centers on a railway-obsessed loner with murderous fantasies, and “The Woman Who Borrowed Memories” presents a case of disturbing transference. Unsentimental, yet always humane, Jansson’s stories complement and enlarge our understanding of a singular figure in world literature.
