The letter-loving trio at Spence Mansion has something to grieve
about--Ghastly's post office is about to close, which will cut off their
connection to their fans. A new invention called VEXT-mail is
threatening to replace not only letters, but books, hair dryers, and
even garage door openers! Could the mysterious occupant of P.O. Box 5
and his seemingly sinister plan save the doomed post office? Will he
strike down Ghastly's beloved ghostwriter in the process? In this fourth
book in the award-winning 43 Old Cemetery Road series, eleven-year-old
Seymour Hope and his new friend, Wy Fye, must solve this postmortem
mystery . . . before it's too late!
