Caesar cipher – Sherlock Holmes’ Solution

I’ve been wacthing Sherlock (BBC Serie) and I was thinking about the “science of deduction” that is presented in the first chapter.

I decided to make a little researching about that on google, and I found Sherlock’s blog http://www.thescienceofdeduction.co.uk

And there’s a hidden message with Caesar cipher.

Sherlock, explains to you how to solve the following message:

‘Hi Sherlock

SOMNEHCCGTEKOTYRIMOOLAIGU

You’ll never find out who I am. I live off the grid.

cheers
xx’

And there is also a “Show Solution” link

Solution:

SHERLOCK I AM COMING TO GET YOU

This is a form of grid cipher. There are 25 letters in the message so it’s easy to work out the factors – 5 x 5! Create a 5 x 5 grid and write the letters in the grid from left to right, top to bottom. The decoded message reads down from top to bottom, left to right!

So I found this really interesting, I hope you too.

Have a nice week.
