Red Tide

A week before her wedding Janien Steyn is found dead, grotesquely arranged on a bike in her wedding dress, with a long red bridal train in her wake, as if in mid flight. Retired policeman Jaap Reyneke asks Sarah Fourie, a hacker with a criminal record and zero social skills, to help solve the case.
Janien was a successful artist and business woman, and on the point of marrying her university sweetheart.

Was it suicide or murder? Why was her body arranged so carefully, almost artfully? And why did she wipe her computer's memory so thoroughly before her death?
