[Bruce and Alfred try to solve Riddler's Clues]

Bruce:
"We're five little items of an every day sort; you'll find us all in a tennis court." In...a...E, I, O, U. Vowels.

Alfred:
Not entirely unclever, sir. But, what do a clock, a match, chess pawns, and vowels have in common? What do these riddles mean?

Bruce:
Every riddle has a number in the question and they write in this order: 13, 1, 8, and 5.

Alfred:
13, 1, 8, and 5.

Bruce:
Maybe, perhaps, letters of the alphabet?

Alfred:
Of course, 13 is M.

Bruce:
1 would be A, 8 would be H, and 5 would be E.

Alfred:
M-A-H-E.

Bruce:
Perhaps 1 and 8 are...18.

Alfred:
18 is R. M-R-E.

Bruce:
[makes a realization] How about "Mr. E"?

Alfred:
"Mystery".

Bruce:
And another name for mystery?

Alfred:
Enigma.

Bruce:
"Mr. E-nigma". Edward Nygma. Stickley's suicide was obviously a computer-generated forgery.

Alfred:
You really are quite bright, despite what people say.
