You slowly roll out of bed, preparing for the day of solving crime ahead of you. After all, you are the greatest detective the world has ever seen. But at work, the mystery you are assigned shocks even you - the president has been murdered! As the greatest crime-solver in the history of Scotland Yard, it is your job to find out the culprit, and get him safely locked up. Judging by what the suspects have said, you are almost certain the killer was Mr. Assassin F. Hire, whose statement was "The old fool deserved to die", but you still have no solid evidence, so you raid his house in his absence; however the search proves fruitless, except for one scrap of paper in his bin. It reads:
Vzthe (UZKkDSc), but what could that mean?
After a few minutes of examining it, however, you clap your hands in delight!
Where should you go next?
Note: This part is incredibly easy, and done mainly because I need somewhere to start.
You slap your forehead in annoyance: of course! A ROT13 cipher. You quickly head to http://imgur.com/HMXxQFp and see:
Clicking onto the main Imgur site, the text 'Is there more inside than meets the eye?' can be seen.
You are certain this leads somewhere, but what secret does it contain?
At last, you realise what the image was: of course! It was
steghide. You Find the text 'Go to XQm0gSH for instructions', and hurry to http://imgur.com/XQm0gSH, where you see a program you instantly recognise as '99 Bottles of Beer' in Piet. Accompanied by the text 'The song's title paves the way', it seems obvious what to do. You download a copy of your program 'Which Bar Was I In Last?' and run it on his computer. You always knew that program would come in handy one day! However it instead writes to the console
FATAL ERROR: /dev/beer does not exist, killing process. Damn, you thought you'd fixed that bug. Annoyed, you stand up, and kick his desk. But then, the lid flips open, revealing picture of a bottle of beer, accompanied by the text '99 bottles in cellar. -Boss'. What could it mean, you ponder. Suddenly, it hits you: he has a cellar! You bolt down the staircase you helpfully ignored during your search, then pull open the door to see... nothing. Aside from the graffiti on the wall, the room is completely empty. But something still peeks your interest down here. Slowly, you wander over to the graffiti. After some careful examination, you realise there's more to it than meets the eye! It reads
ANTT VLR ĒMRSNIRPV. Underneath it is scrawled in a different colour
G=G, V=V LH=(R1) RH=(L1) :: en/lv.
You are certain decrypting this will give you enough evidence to convict him, but what does it all mean?
As @ev3commander worked out below,
ltrefers to the Latvian language. The
enrefers to English, but in a more subtle way.
The Latvian people have various keyboard layouts...
