[a.k.a. THE HOLLOW MAN]
Here is a contemporary review in THE SATURDAY REVIEW (September 21, 1935), archived here:
Murders of London "illusionist" and dabbler in magic reveal Dr. Fell's knowledge of vampires and the black arts. - Imposingly transparent solution of "impossible" crime involves almost too many "traps"—but takes the cake for creeps. - Verdict: Class A.
As Douglas Greene pointed out in THE MAN WHO EXPLAINED MIRACLES (1995), his exhaustive and authoritative study of Carr, THE THREE COFFINS (1935) is that rare exception—a book that can be read with equal enjoyment two, three, or more times, even though the ending is already known. — Edward Marston, THE RAP SHEET (August 29, 2008)
Modern readers are often dismissive of locked-room mysteries, thinking them hopelessly old-fashioned. Yet, as John Pugmire and Steve Lewis point out in an excellent assessment at the MYSTERY*FILE site, these tales have not only enjoyed a robust history but continue to be written and relished today. — J. Kingston Pierce, THE RAP SHEET (September 25, 2007)
Above all, Carr takes risks. He goes all-out to baffle and mystify the reader. Red herrings abound; nothing can be taken for granted. His job is to fix, baffle and misdirect; the reader's job is to see through it all and penetrate to the heart of the mystery before the detective does. And Carr tries to be scrupulously fair. The clues are all in place; in some books, in fact, their location is pointed out with footnotes during the denouement. A Carr book is a Times Crossword Puzzle for detection fans . . . at the height of his powers Carr was the detective writer's detective writer—and THE HOLLOW MAN is one of his very best. — Jon, The GAD Wiki
Certainly not Carr's best work. However the plot, setting, puzzle, clueing and deductions are so superior to much written in the golden age with the result the book has to be recommended as well worth reading. — A. G. McLean, The GAD Wiki
