An example of encryption of the message 'MEET ME TONIGHT AT 8' might be to write the message on a 5 x 4 grid:  

M E E T *
M E * T O
N I G H T
* A T * 8

and could then be sent out as 

MMN*EEIAE*GTTTH**OT8 (reading down each column).

Decode the following message using the same grid :

LCOLIE**CDK*E*I*NTL*
