Cover Art (c) Roger Kopman. In Paris, two bodies have been found floating in the river. Two friends appear in tourists' photographs, side-by-side smiling up into the Heavens, as if this had been nothing more than another Saturday spent happily fishing. Later, a third unclaimed body will turn up at the morgue. When the fourth appears, it's time for Paris sleuths Mrs. Duchesney and Louie Bertrand to get involved. Something very fishy has been happening along the banks of the Seine. What could these four deaths have in common and how is a small boy named Cicero involved? "Demandez au Morse," the worm seller tells Mrs. Duchesney. "Ask the Walrus."
