It is always darkest under the candle. And what about the cemetery!

Only a few steps from the famous Prague shopping center is the area of ​​Olšanské hřbitovy, whose brooding character attracts the attention of fourteen-year-old Klára. All it takes is the gentle encouragement of the old lady Anežka, and the girl soon finds herself among a handful of her peers, who were drawn here by the ivy's silence just as much as she was, because they watch it every day from the windows of their homes. The newly formed group, which also consists of Vojta, Šimon, Evžen and later his sister Běta, will renew the ancient tradition of the Gravedigger standing guard over the peace of the Olšan dead. Thanks to the famous deceased, the cemetery will remind them not only of the memorable moments of our history, but also unravel the tangles of family history, the clues of which were literally under the children's nose until now. Before the self-sacrificing five searchers reveal everything in time from All Souls' Day to the June heat, they experience a series of thrilling moments, because something sinister is brewing among the tombstones. Will old Anežka help again?

The first part of the detective trilogy about the Undertaker goes a long way in defending the black-and-white emo style. The debut of the winner of the Magnesia Litera prize follows the white magic of adventure, which Vinohrady classics František Langer and Jaroslav Foglar did with attentive groups of children.
