One Minute Past Eight — George Harmon Coxe

At approximately eight o'clock private detective Harry Baker stumbled onto something big. At exactly one minute past eight, Baker was dead. The local police had figured that out for themselves. Now they wanted to know the rest from Jeff Lane. But what could Jeff tell them? He had sent Baker to locate his missing step-brother in Caracas. When Baker cabled he had news, Jeff went to Venezuela himself. Now Baker was dead. And, a few days later, so was Lane's step-brother. Jeff was struck by a sudden cold conviction. He was in a strange land, among strange people, and up to his neck in murder.
