Lion in the Valley.

«The Lion in the Valley» — a historical detective novel with an adventurous plot, where an archaeological expedition in Egypt quickly turns into a series of dangerous mysteries, and at the center of events is the family of Amelia Peabody. The excavations at the Dashur pyramids become not only the backdrop for the investigation but also a place where Victorian restraint collides with adventure, crime, and outside interests. This is the fourth book in the Amelia Peabody series, and here family ties, old adversaries, and the tension that arises where antiquities are too costly are especially important. Egypt is not a postcard here, but a working space for archaeologists: a camp, Cairo, caves, rumors, deals, and a constant feeling that behind the next coincidence lies someone's calculation.
For the new excavation season, Amelia arrives with Radcliffe Emerson and their son Ramses, but calm work does not happen from the first days. An attempted child abduction, a suspicious Russian prince Kaleniščeff, and the death of a young aristocrat intertwine into one knot. In Cairo and at the camp near the archaeologists are Enid Debenham and Donald Fraser, known by the name Nemo, and each of them brings new questions with them.
