An eighth and final hint for Challenge 10A
The last word of the message is attached, enciphered as
| a | T |
| t | a |
| c | J |
| e | H |
When the second letter of a pair follows a it seems to be enciphered as itself, but when it follows c it has been shifted by 2 and when it follows e it has been shifted by 4. Can you spot the pattern now? We will leave it to you to finish.
Have fun and Happy Holidays,
Harry and Jodie
