March 1919. Everyone is talking about the third wave of the Spanish flu. After a lull, it lasted all summer, and even though they thought the pandemic was over, the restrictions became very severe. But damn it, not to the same extent! Adventurer Jake Summers returns from Europe after another business - home, in the outskirts of Detroit, where he has recently settled with a companion. One returns: the clever sneak (and future writer) Duke Mallow is stuck in quarantine - unlucky enough to cough at customs. Provincial Blinville, until recently prosperous, has turned into a plague town. All closed. Nothing is possible. A sanitary inspector looks after order in the city. How do you tell an honest swindler to make a living? Moreover, he himself cannot cough without this strict Doctor Banks finding out! What an unpleasant quality some people have - they are always right. But still: there are no coincidences. Everything we need is always at hand. Just like in Mrs. Fox's travel bag, which Jake Summers inherited in his youth, there was not a single unnecessary item. The third book in the series "Five Bucks for Dr. Brown" is a retro version of the adventure series "Madame Renard's Universal Travel Bag" A quest novel about advertising, friendship and what you love, without which there is no happiness in life.
