Christie A. (Agatha) creator us New York Bantam Books 1950 eng 215 p. His name is Mr. Brown. No one looks at him twice: his face is every bit as ordinary and unmemorable as his name.

He is without doubt the finest and the most ruthless criminal mind of the century. n/29553 101112 20260805124025.0 00000000000041437
