Murderous Maths : Codes

Enhanced descriptions from Syndetics:

Will show readers how to encode/decode their own messages in as manyw ays as possible.E xamples of differently coded messages will also fit in well witht he diverse range of the usual MM characters.C ontents would include:- Disguised codes (e.g. see the last para of synopsis)- Scrambled codes (where the order of letters is mixed up)- Substitution codes (where letters are replaced by other letterso r symbols or just 14 21 13 2 5 18 19 )- Some history of how codes have been used in the past, from ancientR oman times to cracking the WW2 German Enigma machine.- Other message systems such as morse code, flags and also activityi deas such as making cut-out stencils that work with code grids.Although the other MM books deliberately avoid exercises or settingq uestions, this title lends itself to setting messages that needd ecoding by the reader, possibly leading up to a mega messaget o decode at the end.Can you see this very last paragraph is coded? (Read all the fourthw ords). The book demonstrates other codes you've probably neverr eally been aware of. Stop waiting therefore and go for it.
