The collection includes two detective novels. “The Millions of Marco Polo” by the Swedish writer Frank Heller, in a light, slightly ironic style, tells how a psychoanalyst from Amsterdam revealed the secret of the famous traveler’s treasures. The non-standard plot and the exciting adventures of the heroes in the mysterious and mysterious Venice allow us to classify this work as both detective and adventure literature. The novel by the Englishman Edgar Wallace, “The Mystery of the Yellow Daffodils,” on the contrary, meets all the laws of the crime genre. Here is a murder surrounded by mystery, and amazing events that defy explanation, and elements of oriental exoticism, and, as usual, a completely unexpected denouement of the whole intrigue.
