Journey for Death. Book One. The Gravedigger from Tallinn

In Tallinn, in the Church of Saint Olaf, an arrow pierces the back of the organist, and in the museum of the Brotherhood of the Blackheads, a folding golden altar by Jan van Eyck goes missing. Klim Ardashev will have to figure out what connects four notes added to the score of the deceased musician, an ancient Roman epitaph on an old tomb, and a battle from the times of the Livonian War. The investigation is complicated by the murder of a Soviet diplomat, the appearance of an old acquaintance from Yalta, and the arrival of the steamship "Paris Commune" with a cargo of gold from Petrograd. And this is far from all the obstacles facing the private detective in August 1920.
