Summary Contractor Holger Ahrens was fatally shot, tied to his vehicle. He employed underpaid employees and subcontractors to fake competition. Niko and Birte Tennberg claim Ahrens's failure to properly connect a pond pump caused their young son to die from a fatal shock. Virtual foreman Valentin Guga, who already moonlighted on the side, now inherits most clients, but suffers non-fatal sabotage himself. Ahrens and Guga's latest, major renovation client Angelika Lorenz and her daughter Daniela Falk discretely have more personal links to Holger.
