content: Published in 1955 - I have never ever cared for this volume and until I read The Mystery of The Aztec Warrior thought it was the worst in the series. To me I always found it a suffocating book and I can't explain why. Tony plays a prominent role in this one and to the books credit at least they encounter the criminals a fair amount and there is a little action. The latter chapters were fairly decent. Its worth reading - once -but honestly compared to the other volumes in my opinion this is among the cellar dwellers. (Almost a 2 Star - but not quite) RATED D
