Death is My Shadow was published as a hardcover by Thomas Bourgey & Company in 1957. The edition that caught my eye is the mass market published by MacFadden Books in 1965. The clean white background perfectly frames the little black dress attired gun toting dame. The artist: Unknown.
The opening paragraph:
“The doctor offered Byrum a cigarette, shoving the pack across his desk. It was hot in Los Angeles, but the air-conditioner that Stein had swindled from Government stores made his office comfortable. Stein was small and dark and totally unmilitary in his khakis, rumpled, sweaty, his beard a dark swath along his rounded jowls. His black eyes were friendly.”
Edward S. Aarons is best known for his Assignment novels featuring CIA Agent Sam Durrell, but he wrote several excellent standalone novels under his own name and the pseudonym Edward Ronns. The Gold Medal edition of his novel, The Decoy, was previously highlighted in a Thrift Shop Book Cover post.
