About the book: 2023 / The book presents two action-packed novels, the main character of which is private detective Igor Gladyshev. In the first of them, “Gop-Stop in Spanish,” he, while on vacation in the Spanish town of Susanna Cruz, meets several Russian tourists and goes with them on an excursion to the famous Adelita Cave. As soon as they descend into the dungeon, a monstrous explosion thunders. The guide dies and the cave partially collapses. Sightseers cut off from the world try to find another way out and stumble upon an ancient skeleton in one of the grottoes. A bony hand squeezes a scroll, which describes in detail the place where Christopher Columbus's treasure is hidden... In the second - "The Mystery of the Sacrificial Lambs" - Igor goes on vacation, this time to Turkey. There, one after another, members of the tourist group, which includes a private detective, die. Clearly there is a serial killer at work. But who is he and why does he kill people who don’t even know each other? Or do they know each other??..
