Professor Ambrosius en het spook van de Murdocks

This Dutch comic series from Semic Press, launched in 1973 and ongoing, follows the supernatural investigations of its titular professor. Written by Lo Hartog van Banda and illustrated by Gideon Brugman, the debut issue introduces a spooky mystery involving the Murdock family's ghost. Though it currently stands at a single issue, the series established a distinctive, atmospheric take on European horror-adventure storytelling.
