Stefan Brockhoff

Stefan Brockhoff is a pseudonym that was used collectively by a group of three German co-authors of several detective novels^[1], all of them having certain characteristics in common: they were all born in Germany at or about the beginning of the second decade of the twentieth century; at one point or another they all of them became refugees from Nazism; and they all eventually lived out their lives in the United States of America. Moreover, to every one of them the writing of detective novels was a youthful avocation, their principal interests and activities in later life lying in different areas.

Dieter Cunz (1910–1969)
Richard Plant (1910–1998)
Oskar Seidlin (1911–1984)
