Think like a detective

 

This is my Think like a detective the secret code 2 was. Look carefully to uncover the clues. Down the bottom, it said to write a message of you're own. So I write my last name Maclaurin. On secret code 3, the code was. This is no red herring. The message I write was my first name Michael and in the secret code Michael was NRXSZVO and Maclaurin was NBDMVBSJO.
