Nancy’s Mysterious Letter is the eighth volume in the Nancy Drew Mystery Stories series. It was first published in 1932 and was penned by Walter Karig, a replacement writer for Mildred Wirt Benson. Benson declined series work when the Depression forced a reduction in the contract fee provided to Stratemeyer Syndicate writers, so Karig, already an established Stratemeyer writer, took over the authorship. Due to Karig having died in 1956, the 1932 version passed into the public domain in Canada and other countries that have a life plus 50 policy, in 2007.

Summary (original edition)

In Nancy’s Mysterious Letter, a misdelivered letter bearing her own name plunges Nancy Drew into a doppelgänger dilemma that stretches from River Heights to London in this transatlantic mystery of stolen identity and postal intrigue. The story begins with Nancy receiving a letter clearly intended for another Nancy Drew—an heiress to an English fortune who shares not only her name but her handwriting style.

The investigation reveals a sophisticated mail fraud operation exploiting transatlantic shipping delays, with Nancy tracing clues from the River Heights post office’s cancellation marks to a local boarding house where ink-stained fingers hint at forged documents. As she deciphers the connection between a missing philately collection and the sudden appearance of British “relatives” in town, Nancy must contend with a rival detective determined to solve the case first—a brash young woman whose unorthodox methods keep derailing Nancy’s careful deductions.

The 1932 original thrums with postal-era suspense—Nancy analyzes watermark patterns under her father’s office magnifier, recognizes how Depression-era stamp shortages facilitate mail scams, and narrowly avoids being locked in a railway mail car scheduled for overnight storage. Unlike later revisions, this version retains the thrilling chase through the dead letter office where Nancy spots the crucial envelope by its unique tear pattern, and the poignant moment when she realizes the real victim is a war widow whose inheritance was stolen through bureaucratic trickery.

This novel stands out for its ingenious use of everyday objects as clues—a pen nib’s distinctive scratch, a wax seal’s hidden hairline crack, even the way a seemingly blank envelope retains faint impressions of its missing contents. The mysterious letter itself becomes a metaphor for identity in crisis—its crossed-out addresses mirroring lives redirected by greed, its surviving postage stamps representing how even broken systems can carry truth to those who know how to look.
