Q.B.I.: Queen's Bureau of Investigation by Ellery Queen [1956 PAPERBACK]

FIRST PAPERBACK PRINTING [1956] POCKET BOOKS

Nice reading copy!  Some general wear to cover and tanning to pages. Binding is loose on the first few title pages (see last photo)

The Letters Racket--A is for Alfred, who left his poor wife ripe for a blackmailer late in her life. B is for Brothers, three of that name, who skewered one morning the fourth Brother's dame. On through the files of Q.B.I., from Bacon to Kidnap to a Poisoner's try. The victims are many, the killers are, too, and only Ellery Queen can find out who's who!
