First Edition. "On a Pacific Liner, coming from China to the United States, there is the absent minded charming old Professor, who thinks of nothing but his archeological specimens. On the same ship are his niece and a young Englishman. All is serene when a sudden and appalling tragedy takes place. In San Francisco, across the Continent, in New York Peter Clancy, like a dog on the scent, follows clue after clue, until he finally finds the cause of the Pacific Mail Steamship crimes". Very scarce title. Very Good in Good fragile dustjacket, fading and staining to spine, inch sized chips at spine ends.
