WHEN (NOT) IN ROME

by Greg Brume

Solution: TINTED WINDOW

The grid is filed in as follows, using only the letters in TIEDOWN.

D O W A G E R D E B I T
O H R E I E E
R H I N O V E N I S O N
S S W E T E D
A N T E N N A E Z E R O
L U L K C N
L E A P T W I G H T
O N S D N E
C I T Y D E C K H A N D
E R O A A C I
L E A R N E D J O I N T
O N E L O N O
T U T O R Y O U N G E R

Working with the numbers on the side, it's possible to determine that, much like Roman numerals, T=1000, I=500, E=100, D=50, O=10, W=5, and N=1.

Translating the account number in this system, you'll get TIN-TEDW-IN-DOW. Respaced, this gives you TINTED WINDOW.
