When zoologist Magrieta Prinsloo is put on the wrong antidepressant, her head comes unstuck. She insults the head of her department, and impulsively resigns from her job. She accepts a position at the Bureau for Continuing Education, with the inscrutable Markus Potsdam as her boss. When he disappears one morning, matters become very complicated. Winterbach's extraordinary gift as a novelist, and uncanny understanding of the human psyche, are again as evident as ever.
