After Cassandra Cass is shot in her bed (by a mysterious hooded figure) while her butler draws her bath, it is revealed that she has been blackmailing subscribers to her society Blue Book. One after another of the suspects (a deposed Balkan King, a banker, a drugged out socialite and the head of a ""psychodrama"" society) more or less confesses to the crime, but each of their descriptions of the event varies slightly from the known facts. Meanwhile, Les keeps insisting that ""the butler did it"". With the help of Cassandra's sexy secretary and a health fanatic, Burke concocts a plan to trap the real killer.

Granny Grabber, the not-so-nice head of a toy firm, is blown sky high by a bomb placed in his giant toy soldier cigar lighter. The killer had to be one of five people who were photographed coming into his office that day (Granny was paranoid about industrial espionage). The victim's sultry secretary, the company's military adviser on all war toys, an aeronautical scientist, a ""James Bond"" wannabe, and the head of a school for juvenile delinquents all come under suspicion. When one of the suspects discovers a vital clue and is murdered, Burke discovers that Granny had plans to make millions by NOT producing a toy!

An ace shot by a tennis star blows up in his face at a charity event, after one of his tennis balls has been loaded with explosives. Burke scours the local country club for clues while trying to avoid the ""help"" of an eager ball boy, who claims he can solve the case for Burke. The victim's pessimistic manager, his fiancee and her jealous sister (a dentist), his ex-wife, and a tennis rival all had access to the club room and could have tampered with the equipment. Finally, a nightclub singer who knew the victim well gives Tim some valuable information. When Burke figures out the relevance of a casual bit of trivia, he corners the killer, who still has a few ""bomb balls"" to spare. The case comes to an explosive finish.

A big business wheeler-dealer, formerly part of a carny consortium, meets his end after injesting cyanide - but he didn't eat or drink anything that had been tampered with. The suspects all formerly worked with the victim in the carnival racket and are now heads of powerful companies: a health club president, a fitness tonic manufacturer, the producer of fancy lingerie and the head of a think tank. Only one of the old gang hasn't made it big and now runs a local merry-go-round. When Les almost dies of cyanide as well, Burke discovers the murder weapon in an unlikely spot. He then turns the tables on one of the carny con artists and nails the killer.

At Raff's International Circus, 13 clowns pile into a tiny car, but only 12 come out alive. The thirteenth has been skewered. It turns out that he had been blackmailing several members of the circus troupe. Was the killer a fellow clown or, maybe, his wife? The circus owner or the performer with the fabulous nose? Or perhaps it was the seductive aerialist? While investigating the three-ring case, Burke performs backflips on a trampoline, comes face to face with a surly lion, and then disguises himself in the victim's clown makeup and outfit to trap the guilty party. After a wild, outrageous chase, the killer is finally cornered.

With Burke out of town, Tim, Les and Sgt. Ames have to discover who is responsible for the murder of a blackmailer found propped among the mannequins in a department store window. Les is intrigued by the store owner's executive secretary, Tim follows the head of ladies' fashion, a race car enthusiast, and Sgt. Ames tracks down a nightclub comic who works days as a bus driver. The owner's son and a shifty sidewalk pitchman also come under suspicion. After the man who found the victim is himself killed, a winning racetrack ticket proves the final clue to the murder.

Author Graham Tree is poisoned at a party celebrating the publication of his new book. Tree miraculously survives and now it is Burke's job to find the killer before there is a second - successful - attempt on Tree's life. But Tree refuses to talk. His books, however, have created several notable enemies. Burke, in disguise, tricks the victim into revealing information that leads him to the killer. Was it the playboy, the polo player, the ruined oil man, Tree's publisher, or his socialite former flame? The would-be killer strikes again - will Burke get there in time?

When a wealthy physician is shot, his wife disappears. It seems she has a habit of running away when things get tough. Is she the murderer or another victim? Burke finds out more about her unhappy history from her sister at an amusement park, tracks the missing woman's past through a gambling casino, a lonely hearts club, and a waterfront dive. The other men in her life (also possible suspects in the case) include a ship's cook, a con artist ""hypnotist"" and an ex-jockey. An anonymous note proves to be the clue that reveals who the real murderer is. Burke arrives just in time to prevent another murder.

The head of a greeting card firm was killed, but not by the arrow protruding from his body. It was slow, methodical arsenic poisoning. His flirtatious teenage assistant takes a shine to Burke, but he's afraid she may be the prime suspect. If not, there are several others to choose from: the victim's ambitious successor, the mousy psychologist and his domineering wife, or the jingle writer. Burke's intentions are misunderstood and he comes close to being a second victim. The series ends with the whole cast of regulars involved in a big musical production number (of dubious artistic merit).
