understanding of space travel. In the narrative, Captain Douglas faces significant delays caused by his bo'sun, Tug Skelly, who inadvertently brings chaos to the ship by chasing a stowaway. As tensions rise, they consider an ancient and risky route, the Cross Straits, rumored to be guarded by mythical witches. Tug's reliance on superstition leads him to perform a "ritual of purification," resulting in the ship's hull being painted with the valuable platinum meant for cargo. As they navigate through the perilous Straits, Douglas and his crew confront both the consequences of superstition and the unyielding nature of scientific principles, ultimately arriving at a greater understanding of their experiences and the importance of empirical knowledge.
