Spoiler:

Superintendent Anthony Slade arrives on the Riviera in search of lovely Gloria Kincaid. Before he finds her a killer strikes, and she dies with laughter spilling from her lips. In the company of Inspector Henry Duval, of the Sûreté Nationale, Slade faces one of his most puzzling cases. The two detectives, who worked in double harness previously in The Frightened Chameleon, now have to find a murderer who strikes again, and yet again.

Slowly the weft and woof of a tangled skein of mystery unfolds into a pattern of almost unbelievable duplicity. A white Jaguar crashes on the Grande Corniche. A yacht steams first into French waters, then Italian, then back again. Marcus Mordayne, one of the more florid wayside blooms along the torturous path of international crime, provides his own complications, for his own personal reasons. Tragedy unfolds in a deserted house in Juan-les-pins. Such facts provide the painstaking Yard man with pieces that fir into an extravagant jigsaw of human emotions.

The Glass Alibi is in the Anthony Slade series, at $0.99 for about 1/2 more day, before going to $1.99 for an unknown amount of time.

Spoiler:

A young man is caught up in a mystery that begins for him when two plain-clothed men approach him one night outside his flat. From that moment his life changes. By the next morning he is a subject for newspaper paragraphs and he knows what it means to live the furtive existence of a fugitive.

For a week that strange double life continues, always under the eyes of Slade, who is hunting a callous murderer. It is possible that he would not have continued with this desperate game had it not been for lovely June Kragle, herself sought by the police. The two make a bid to help the police - only to find that Slade takes the rubber in a thrilling finale that breaks a killer's glass alibi.
