Geoffrey John Barrett
(1928 - 1999)aka Edward Leighton, Dennis Summers, James Wallace
UK writer who also published thrillers as Cole Rickard and Westerns as Bill Wade; his sf novels, written for Robert Hale Limited under his own name and as Edward Leighton, Dennis Summers and James Wallace, are consistently routine; as there seems to have been no intrinsic reason for selecting these different names, Barrett's sf is listed below as a single chronology.
