Letter of intent Problem 184 — Reading between the lines is sometimes easier than reading under them, as this month’s problem by Gary Baylor of Yardley, Pa., demonstrates.
It was 10:00 p.m. and the chase was on! The agile spy bounded over fences and low rooftops as a pack of policemen, detectives, and representatives of various government agencies huffed after him. Too late! The spy plunged into a wellknown embassy and into diplomatic immunity.
Detective Inspector Schnoop wrung his hands and muttered an oath. A certain nation’s latest international scandal would certainly be the top story of the hour. A scrap of paper dropped by the spy indicated he was about to alert the media. On the paper were the figures:
The chase had been the culmination of a six-monthlong investigation. The embassy had been funding a secret group of agitators who had been traced to four empty houses in a seldom-traveled street. Unfortunately, the police had been unable to ascertain which houses. The numbers on the street ran from 123 to 1075.
Schnoop suddenly stopped in his tracks and stared at the scrap in amazement. Let each letter stand for a unique number between 0 and 7, inclusive — no 8s or 9s. What were the house numbers? Will Schnoop and his cracking of the case be the highlight of the 11:00 p.m. news instead?
