Letter Bound

My lungs are killing me. I don't know how long I was asleep atop of that book shelf, but I think I have breathed in enough dust to choke a horse. Or in this case, a time travelling dog. The last thing I remember seeing were a few letters. H U G? What sort of clue could this give me. Perhaps ol' Hambriddle went off to give some people some hugs...but I doubt it. The only thing that guy would hug would be a dictionary. Possibly a thesaurus.

So I sit here covered in dust when I receive a call from my scientist Pal from the future. It says, "Not to concern you about anything, but the future just changed again. It looks like a lot of the words using a H, G, and U are sort of fading away. People are having a hard time hugging eachother instead opting to go right ahead and kiss. Times are changing, Future Dog!"

Well drats. I pick up the three letters that seem oh so vital to preserving the future. Just three letters are changing this much? I don't even want to know what else could happen. You would think they would just adapt to not having the letters, instead, opting to make up some new ones that mean the same thing. They're just symbols for goodness sake! I need to solve this case before I stress out even more. HUG...it has to mean something else other than wrapping your arms around someone...or something.

Wait, the tower in town. The Harold Ulcer Grant tower! I think he went there for some odd reason. Suffering from ulcers maybe? He could be stressed out because he's having a hard time collecting all of these letter. I wonder. I have to get there fast. Till next time!
