The blue book
(Book)

"First published in Great Britain in 2011 by Jonathan Cape"--T.p. verso.

While on a transatlantic trip with her soon-to-be-fiance Derek, Elizabeth unexpectedly runs into ex-lover Arthur, with whom she shares a shady past: the pair once worked as traveling spiritual mediums who conned the vulnerable by pretending to contact the spirits of departed loved ones. While Derek remains seasick and cabin-bound, Elizabeth wanders the ship, alternately avoiding and seeking out Arthur. Unable to avoid memories of their fractured past, she must face the deception they practiced even as she accepts the peace they brought to the grief-stricken who sought their services.
