"The Red Room" by William Le Queux is an early 20th century mystery that centers on Kershaw Kirk, whose link to the murdered Professor Greer pulls an unwitting motor engineer, Mr. Holford, into a dangerous investigation. The story kicks off on January 15, 1907, when Kirk, shadowed by secrecy, asks Holford to examine a German tyre, alluding to a deeper, more sinister connection. Their unsettling alliance forms the base of the novel, as Kirk admits his involvement in Professor Greer’s murder, which happened not long after their meeting. As Holford navigates the twisting currents of suspicion and secrets, the stakes soar when the Professor’s daughter dies under equally puzzling conditions, setting the stage for a thrilling story of deception, where the truth remains obscured.
