Introduction

Two blank sheets of writing paper sealed in an envelope with a postmark from Baskerville are brought to Holmes by London publisher Garrison Bolt.

The addressee is Newman Musgrave. Together they must investigate why this letter, which contains a hidden secret, was sent with such urgency to a man, who unbeknown to the sender has been dead for a number of years.

Or is it possible that this note was never intended for the deceased man, but rather deliberately intended to fall into Holmes's hands?
