is made to
PROFESSOR ALEXANDER GOETTLER

for his friendly offices
in the preparation of this tale
<p><emphasis>Lexicon of Persons Connected with the Investigation</emphasis></p>Note: The complete list of individuals, male and female, brought into the story of Monte Field’s murder and appended below is given solely for the convenience of the reader. It is intended to simplify rather than mystify. In the course of perusing mysterio-detective literature the reader is, like as not, apt to lose sight of a number of seemingly unimportant characters who eventually prove of primary significance in the solution of the crime. The writer therefore urges a frequent study of this chart during the reader’s pilgrimage through the tale, if toward no other end than to ward off the inevitable cry of “Unfair!” — the consolation of those who read and do not reason.
