Why is Alfred Hitchcock's face on the covers of
only the first three hardback books?
Readers and collectors who have the first
three mysteries of the Three Investigators in hardback
may have noticed that Alfred Hitchcock's face appears in
the cover paintings of all three books. In the first
cover ("Terror Castle"), his face is set in
part of the bricks of the wall in Terror Castle; in the
second cover ("Stuttering Parrot"), his face is
on a bust on the file cabinet in Headquarters, and in the
third cover ("Whispering Mummy"), his face is
on the wall wearing the headgear of an Egyptian noble,
probably a pharaoh.
