Ghostspeaker. Malykant Mysteries, #4

Konrad Savast is the Malykant: foremost and most secret servant of the God of Death. His job? To track down the foulest of murderers and bring them to The Malykt's Justice. No mercy. No quarter. A sparkling society ball is held at Bakar House - but its success is overshadowed by the subsequent suicide of one of its guests. There was something strange about Miss Dominka Popov, but when Konrad is sent to investigate, he learns the strangest truth of all: her death was neither suicide, nor murder...
but both. How could this be? When Konrad delves into the victim's past, he uncovers a host of strange family secrets. Assailed by the combined perils of society gossip, an unregistered Ghostspeaker and a host of unquiet spirits, Konrad will need all of his wits - and the help of his closest friends - to discover the truth.
