Lucky Starr and the Big Sun of Mercury, by Isaac Asimov - Stranger than SF

Science Fiction Book Review ★★☆☆☆ There's a saboteur on Mercury who is stalling progress on an important scientific research project. Lucky Starr solves the case. I found this installment in the Lucky Starr series to be below par, mainly because I didn't believe the motivations of the guilty party. Also, the title is misspelled on the cover.
