Pam and Jerry North lead a strange chase among old bones to catch a killer.

When Dr. Orestes Preson, distinguished and scholarly mammalogist, found that someone was inserting classified newspaper advertisements in his name, requesting candidates for various unlikely jobs to appear for interviews, he called in the police. They weren't much interested. Their interest became lively when Dr. Preson's sister was discovered drugged in his apartment, and acute when a definite murder attempt was made.
Pam and Jerry North come into the picture since Jerry is Dr. Preson's publisher, a happy publisher, too, for the learned Curator of Fossil Mammals has the touch that converts research into bestsellers. Soon they are very much involved in some strange doings among the cases of ancient bones in the Bradley Institute of Paleontology.

Sergeant Aloysius Mullins and Captain Bill Weigand assist the Norths as they get into full swing in their sixteenth mystery. In a setting reminiscent of cave man days, a strange game of hide- and-seek is played out. The climax is a wild chase in which Pam emerges the heroine.

Pam and Jerry North have given pleasure to hundreds of thousands of mystery fans. Their latest adventures furnish another example of why the Lockridges, through the years, have attracted so large a following.

People who haven't discovered Mr. and Mrs. North Mysteries are in for a treat. I like them better than Nick and Nora Charles. Other couples mysteries that are worth a look are: Agatha Christie's Tommy and Tuppence series and Takis and Judy Iakovou's Julia and Nick Lambros series.

When the poisoned Bowery bum turned out to be a missing Senator, Lt. Weigand was glad that Mr. and Mrs. North were not involved. Then he found that they knew the murdered man -- and were just wacky enough to put their own heads into a noose trying to untangle this bizarre, baffling case.
