Dear Dr. Deuterium:

I am writing with very distressing news. Two days ago one of our colleagues, Zinthane
Zirconium, was found in his laboratory. Not uncommon I guess, except he had expired, the
victim of foul play. The police are baffled, because he apparently stopped
br
eathing

after
snacking

on his morning sugared fruit and bagel. We are calling on you to help if possible, as
we know you were lifelong friends with Zinthane. After all, he did develop the cut
-
free cover
on all the golf balls you lose. Please help us if
you can. I have taken the liberty of giving you a
list of suspects, and the following page is the forensics report.


Here is the suspect list:


Horatio Hydronium


He is apparently tied to a foreign agency, although we cannot prove it. We believe he has
been
passing secrets to them via the internet, by using coded messages. He has been upset with
Zirconium ever since his thesis titled
“Polar

Bears Get Cold Too” was discredited by Dr. Z
because the research was faked in Hawaii.


Molly Molybdenum


She is

a real piece of work?
After

14 years as a professor of metallurgy at MIT, she became an
arsonist. After her release from prison, Dr. Z hired her to work on his newest project;
cryogenics. She has been very cool toward his ever since.


Cory Colloid


Th
is guy has been suspected from more jobs than you can imagine. He was just removed from
the lab last week for violating procedures. I heard he attempted to separate an azeotrope.


Dr. Natasha Neutron


She is extremely unreliable. When she is around thin
gs get heavy. Her claim to infamy goes
way back. In high school she and Dr. Z dated, but he broke
-
up with her because she was
unstable.


Professor Argentum


Is this man a gold digger! He has been competing with our lab ever since he can remember.
His

jealously of Dr. Z is coming knowledge. He is so whacko, he went on the Tonight Show and
claimed to have been with Hydronium in Hawaii, and assured everyone there is a cold region
called Kelvin’s Half
-
Acre there.


In closing, I beg you to come to our
assistance; we are in dire need. Thank you for your tie and
cooperation.




Sincerely,





Professor Vernal Vanadium

osition unlike any used in the lab

Similar molecular structure to some hallucinogenic

Melting point 177.8 F

Granular mixture in bottom of Dr. Z’s thermos:

Mixture of a soluble substance and an insoluble perhaps

“carrier” substance


Test Results:
