.واختفى منذ ذلك الحين
Und seitdem ist tote Hose.
Pero ya no lo he encontrado en casa.
Y no parece ser un incidente, ¿o sí?
Pero ya no está en su casa.
Y no parece casualidad, ¿no crees?
Depuis, il a disparu,
mais aucune trace d’un crime, alors bon…
Da allora è scomparso e non sembra 
sia stato compiuto alcun crimine, che storia!
Desde então nunca mais apareceu.
Sem indícios de incidentes.
И больше я старика не видел.
