The Ka of Mathias Schinkel

When the ghost of the murdered Professor Mathias Schinkel runs into the spiritualist meeting held by Evadne Pringle, it makes the news. But the killer is also watching the television and orders her death. Saved by the mysterious F.F. von Strelitz, an associate of the murdered man, Evadne is given a new identity. But as events unfold, and his story keeps changing, she becomes convinced that she has been drawn into something illegal. However, von Strelitz did have an ulterior motive, which neither Evadne nor The Ka could have guessed.
