Don't worry about it. I read my murder case, I don't know, like 20 times before I posted it, but I still had mistakes and had to edit it!
I still have no idea about the solution , but I have a question
I'm glad you didn't kill the Professor!
Welcome to the Den! That answer isn't correct. I compose my riddles so that each line gives a letter or two or an entire word that you need to assemble in the end to get the correct solution. So the overall solution of the riddle doesn't have to do anything with the lines. Check my previous ones they are all marked as "What am I?" (with a number in brackets) so you'd know exactly what I'm talking about! But nice thinking, I understand why you thought that could be the right solution.
Have fun!
