The Greek Coffin Mystery

Both editions are collected and they are distinct settings, not shared sheets. US: Frederick A. Stokes Company, New York, 1932, 370 pages. UK: Victor Gollancz, London, 1932, 302 pages, in publisher's black cloth lettered red on the spine (two dealers describe the Gollancz cloth; one reads the spine lettering as pink, likely a faded copy). Which of the two appeared first is not documented in any source consulted: the census claim that Stokes precedes Gollancz could not be corroborated and should not be relied on. Fourth Ellery Queen novel.
