This is the second in the Johnson Johnson series and it's almost as defeatingly involved as the first (The Photogenic Soprano, 1968). Young Sarah Cassells is a flip young English hipster who suspects that her free-loading playboy of a father was murdered. Her investigation leads through the back streets of Ibiza, into an environmental art gallery and jaded jet set parties, as it all connects, somehow, with international intrigue and the planned theft of a sacred necklace. Johnson Johnson, the undercover agent who fronts as an artist, finally manages to clear everything up but like op art, the chief impression is disorientation.
