The real danger of taking an ocean voyage, as I know from sad experience, is that a chap is frequently trapped onboard with some human gumboil or gawdhelpus whom he would go miles out of his way to avoid on dry land. So when Jeeves presented me with a sort of bouquet of brochures for five different cruises, I was keenly aware that only the most fastidious research into the matter would ensure a peaceful voyage for Bertie Wooster.
The liners were named The Atlantic Star, the Queen Mary, the Oceanic, the Savannah Princess, and the Stella Linda, departing (in no particular order) on June 12th, 15th, 16th, 21st, and 22nd. I forget for the moment which went where, but the destinations were as follows: Bermuda, New York, Havana, Rio de Janeiro, and Nova Scotia. I instituted inquiries, and learned that four of the cruiseliners would be populated by various fiends; it seems that my fierce Aunt Agatha Spenser, the dreaded Honoria Glossop, the frightful blighter Roderick Spode, and the alarmingly mush-headed Madeline Bassett would each be taking passage on a different one of these vessels.
The following 8 clues reveal what is known of the five ships. Can you tell what fiend in human form was travelling on what ship, on which day, to which port - and which voyage was safe for Bertram to take?
