A Grave Must Be Deep! (The Argosy Library)

Nobody had much use for wealthy old Uncle Eli Proudfoot when he was alive, so there was not much sorrow when he was murdered at Morne Noir, his Haitian estate. Seven of the eight people who were named in his will were eager to have it read. The will stipulated that he was to be buried with voodoo rites, and it was quite clear where his entire estate should be given. But when that recipient was discovered dead, the eighth person—Patricia Dale—became the prime suspect... and she was to be the recipient of the grim business of the Haitian voodoo sect as well.
