"Rookie Crown Gets the Lowdown on a 'Suicide' When Georgie Puts Her Wits to Work for Him!"

Rarely, very rarely, is "Watson" a smarter detective than "Holmes," and it's practically unheard of when "Watson" is a woman; so when rookie cop Bill Crown unravels a murder made to look like a suicide, it's a good thing he has Georgie and her inside information to help him. Of course, there's the little matter of surviving long enough to tell the tale:

. . . THE shadow seemed grotesque and misshapen, not human, until I realized it was that of a man doubled over with a burden on his back. I knew what the burden was, and my heart started pounding like a kettledrum.

The bottom line:

One must never set up a murder. They must happen unexpectedly, as in life.
