Outline of Headline Cipher

The Headline puzzle enciphers five newspaper headlines with a matrix derived from a Keyword, a Hat and a Setting. Here is an example:

Keyword: JAVELIN 
Hat: BALLISTA 
Setting: SWORD

A key block is set up from the Keyword and then stripped by columns in order determined by the Hat to form the mixed alphabet:

BALLISTA
31564782
JAVELINB
CDFGHKMO
PQRSTUWX
YZ

Mixed alphabet: ADQZBOXJCPYLHTVFREGSIKUNMW

Finally the enciphering matrix is built from the mixed alphabet and the Setting. The mixed alphabet forms the top row, representing plaintext characters. The Setting is written vertically in rows 1 to 5, below the first letter of the mixed alphabet. Then the remainder of the mixed alphabet is written in:

plain adqzboxjcpylhtvfregsikunmw
row1  SIKUNMWADQZBOXJCPYLHTVFREG
   2  WADQZBOXJCPYLHTVFREGSIKUNM
   3  OXJCPYLHTVFREGSIKUNMWADQZB
   4  REGSIKUNMWADQZBOXJCPYLHTVF
   5  DQZBOXJCPYLHTVFREGSIKUNMWA

The first headline is enciphered with row 1, the second with row 2 and so on. The five Headlines:

Third Estate decrees National Assembly.
King orders closure of Estates.
Crowd runs riot, Bastille stormed.
Violence against nobles as many flee.
Citizen Louis Capet guillotined.
