Not sure which letter you're missing so here's a list.
M-upper Left corner
L-in the leaves above the "OM"
S-one middle notice
W-right upper corner
D-Lower left corner, under leaves
Y-under the D
B-to the right of the Y
U to the right of the B
T-right hand side, next to the upper diagonal notice /,starting from the bottom.
Now that I probably really confused you if you go to Gamezebo Tips&Tricks, they have a walkthrough with a picture you can look at.
