Lost letters have only one hope for survival . . .Inside the Dead Letters depot in East London, William Woolf is one of thirty letter detectives who spend their days solving mysteries- missing postcodes, illegible handwriting, rain-smudged ink, lost address labels, torn packages, forgotten street names - they are all the culprits of missed birthdays, broken hearts, unheard confessions, pointless accusations, unpaid bills and unanswered prayers. But when William discovers letters addressed simply to 'My Great Love', his work takes on new meaning. Written by a wistful woman to the soulmate she hasn't met yet, the missives capture William's heart in ways he didn't know were possible, and soon he begins to wonder- Are these letters truly lost? Or might he be the intended recipient - could hebe her great love?
