The Artless Heiress: It's one thing, Miss Columbine Drugget, to handle a classroom full of young girls. It's another thing for a young lady like you to run an Arizona motel for a year at a profit! But that's what your father's will requires. Sam Jones feels a little bit apprehensive about your accepting such responsibility. But how do you think he'd feel if he could see the .38 automatic, the set of burglar's tools, that mummified hand and $40,000 worth of freshly-stolen unset gems in your baggage, or don't you know about all that? Chain of Death: Colin MacLeod's life hangs by a beautifully slender gold chain, a chain given to her in error by that friendly Dr. Fowler on the Guatemala-bound airliner. She had deliberately chosen the off-season to make the flight, and now she is caught in a spider web of intrigue and murder for no good reason! There's a sound in the blackness at her door, a sharp click, then labored breathing. Someone in her room! The slender chain has meant death to four men and terror to a whole country. Is this her rendezvous with death? Without a Trace: Frank Rand is boiling mad! An anonymous note has warned him to stay away from Holly Porter, the girl he loves, because she's "bad trouble". When he races out to see Holly, he finds her and her father tense, frightened, and then her father asks him to stop seeing her! A police sergeant is killed right in front of the Porter house, and a few days later, there's a second killing with the same gun, and Holly Porter is the no. 1 suspect, with a neat stack of evidence against her!
