Private I

6 has a problem.
Everyone knows that 7 is always after him. Word on the street is that 7 ate 9. If that's true, 6's days are numbered. Lucky for him, Private I is on the case. But the facts just don't add up.
It's odd.
Will Private I put two and two together and solve the problem . . . or is 6 next in line to be subtracted?

Private I must find out who is responsible for the disappearing clocks and watches in Capital City before they run out of time.
