C. S. Forester

"Plain Murder" by C. S. Forester was first published in 1930, public domain. A plain delicious murder! In an advertising agency, there are three workers who want more power and they want it sooner than later. With a foolproof plan they execute a plain murder which opens a Pandora's box of power plays, lies, blackmailing and more murders. With one of the three being more hungry than the others, one way or another they all have to face their doom.
