It would have been the perfect murder, but by chance, the body of the foreign woman is discovered during construction work! She hasn't been in the support pipe, which must be driven deep into the Harle for the stilt houses, for long, having been killed by a gunshot to the head. Who is she? Paradoxically, her DNA matches one of the two skeletonized bodies that were found walled up in the old bakehouse on the Jansenhof some time earlier. It is clear that they had been there for over 30 years. More shots are fired. A trail of revenge and death stretches along the coast into the hinterland.
