Hopefully, This Investigation Won't Require 39 Steps

In an otherwise routine article in the Wall Street Journal Online ($ubscription required) concerning the London bombings and various issues relating thereto, the following paragraph caught my eye (emphasis added):

Although there have been a number of racially and religiously motivated hate crimes since the bombings, there have been fewer than experts expected. Some caused serious injury, but others did not cause serious damage, according to police. Police Commander Alfred Hitchcock told the press conference in Leeds that the police had already made five arrests in the case of a gasoline bomb left at a mosque.

Need a clever film tie-in for your Police Commander Alfred Hitchcock-related blog post in the coming weeks as the British investigation runs its course? Any of the following titles will probably work for you:

• Murder! (1930)
• The Man Who Knew Too Much (1934, 1956)
• Sabotage (1936)
• Suspicion (1941)
• Saboteur (1942)
• Notorious (1946)
• Dial M for Murder (1954)

Less likely to be useful, however, will be the following:

• Young and Innocent (1937)
• Shadow of a Doubt (1943)
• I Confess (1953)
• The Wrong Man (1956)
