When all the carved-up parts of Van Overbeke's corps are finally found, the autopsy mysteriously shows no violent or other specific cause for his fatal heart failure. The team discovers Frank Leuridon had an adulterous mistress but still no alibi. Her alcoholic husband MD Weyns's violent reaction gets Tibo injected with a fast-working and -broken-down poison, which fits the autopsy. Van Overbeke's private life proves relevantly sanctimonious.
