<spoiler> ANSWER: Murder at the Vicarage </spoiler>

<spoiler> Not the answer yet, but I thought I'd cross post some of the more important information from the Neowin forums:

The answer seems to be related to Agatha Christie as all the pictures match a form of murder in her books:

• Ukulele String 1/8 The Bird with the Broken Wing' (short story in The Mysterious Mr. Quin)
• Marble Clock 1/11/47 "And Then there Were None";
• Apple Bobbing Tub 7/10/17 "Halloween Party"
• Dagger 6/4/16 "Murder on the Orient Express"
• Raincoat Belt 14/13/62 "Three Blind Mice"
• Crowbar 5/39/57 "Witness for the Prosecution"
• Tennis Racquet 3/2/11/7 ("Towards Zero"); "Murder at the Vicarage"
• Golf Club 1/4/6 ("The Murder on the Links")
• Chocolate 9/14/2 "The Chocolate Box"
• Nylon Stocking 1/6/40 "A Pocket Full of Rye"
• Fire 32/28 "The Mysterious Affair at Styles"

Also, using the colors of the fireworks, you can decifer 13124 into 'right' therefore, the clue is "A DEATH CHASE, AM I RIGHT?"

Here's me hoping this spurs someone to think of the answer.

It's worth noting that the clue anagrams to "DAME AGATHA CHRISTIE" with an "H" leftover. </spoiler>
