<h5>Hill Cipher - Known plaintext</h5>
Our spy has intercepted this message. It contains the meeting place of double agents working for our enemies. Unfortunately, we haven't decrypted it yet. <br><br>
The only hint we have is the name of the author that our spy has been able to identify: BROWN. <br><br>
Good luck.<br><br>
PS: the flag is 42CTF{THEPLACEOFMEETING}
