Of Sins of Sumuru, the Manchester Evening News wrote: Dr. Fu Manchu, Sax Rohmer's celebrated character, gives way to a woman -- Sumuru --in this new novel. But Rohmer's sure touch remains. His feminine epitome of wickedness is as fine a piece of imaginative character drawing as the notorious doctor, and the suspense of a well-knit plot never relaxes one iota. Slaves of Sumuru is another equally absorbing of Rohmer's stories of mystery and imagination -- a story of murder and violence -- again featuring the enigmatic woman who all men feared and few men knew.
