Book by Wallace, Ian

Claudine St. Cyr, heroine of Deathstar Voyage, is back in an exciting new science fiction adventure. This time, trapped on a strange planet in a distant galaxy, she attempts to solve an intriguing double mystery—-the theft of a fortune in jewels and the simultaneous disappearance of a royal heir.

Envoys from Earth The two of them were hand picked for the mission to the distant planet of Turquoise. Detective Captain C. St. Cyr combined in a unique way the qualities of lightening fast intelligence and dazzling inborn intuition. Detective Lieutenant U. Tuli was unsurpassed in her blending of computer-like logical abilities and almost religious devotion to duty. Now both of them were heading for the most disturbing trouble spot in the galaxies - to deal with a dark threat to the perfect harmony of the interplanetary confederation.

There is only one way to reach Iola, where an interstellar distress signal had originated. For Iola belongs to a small group of stars cut off from the rest of the galaxy by the close presence of an all-enveloping black hole. The only way to reach Iola is through that timeless-spaceless cosmic warm. Klaus Heller answered that call. He leapt, clad in a special self-sustaining spacesuit, through the black hole. He returned to the world intact, silent, and secretive. And was found murdered where none could have reached him. Ian Wallace's classic novel is a combination of scientific paradox, social innovation, and super detection. Meet Claudine St. Cyr, future sleuth extraordinary, and meet again the mastermind Croyd. Confront with them the murder of a hero, the strange doom of his sister, and the plotted assassination of an entire planet!
