The Edgartown Library will host Peter Hufstader, the author of the new seagoing thriller The Riddle of the Graveyard, on June 7 at 7 p.m.

The story is set on a fictionalized — but accurate — version of Martha’s Vineyard after World War II.

Joining Mr. Hufstader will be Jan Pogue, formerly of Vineyard Stories, who oversaw the publication of The Riddle of the Graveyard, and Lane Gregory, who created the book’s cover illustration.
