Famous Fictional Detectives

What a difficult challenge this was! Sheila from Canada has chosen "Famous Fictional Detectives" as the theme for her tip-in journal pages (each single page measures 4 3/4 x 7 inches). Maybe you think, "why difficult? think of Sherlock Holmes, Hercule Poirot, Philip Marlowe, Sam Spade, and so many others!" Well - yes, but ... this is an international tip-in pages swap, and as I´m not the only one who has to make pages for this theme, and the other participants are from the United States, England and Australia, I decided to go with fictional detectives from German literature. Sheila probably will have to google Nick Knatterton and Emil Tischbein, but I think that most German people have heard of them: Nick Knatterton is a detective from a graphic novel by Manfred Schmidt that was published in a German magazine between 1950 and 1959, And Emil und die Detektive is a childrens book by Erich Kästner published in 1929. I know that Sheila taught Canadian literature, so I hope that she´s interested in finding out more about German literature, too.
The pictures don´t show that the strip of criminals in the Nick Knatterton spread above can be pulled horizontally in order to change the face shown on the "Wanted" poster.
