**Cool & Lam Mystery #4** (1941) When secretary Corla Burke mysteriously vanishes from her place of employment, her fiancé's father, Arthur, Whitewell, hires Bertha Cool and Donald Lam to investigate. The lady may have taken a powder, but she left her purse right there on her desk, money and all, near the correspondence she quit typing in mid-sentence. The sole potential clue is that, on the day before her disappearance, she received a letter from someone named Framley in Las Vegas. Yeah, Vegas, baby. Only, at least one player is bent on stacking the odds.
