Bonnie bought a bag of birdseed. She left it in her apartment (#5) before she went to work, intending to fill the feeder that afternoon. But when she got back, the bag of birdseed was gone!
There were four other people living in the same apartment building as her, all of whom were avid birdwatchers like Bonnie. One of them must have done it. Look at the clues below. If you know everybody's name, apartment number (#1 through #4), and favourite bird, you will know who is guilty.
1. The guilty person's apartment number is not numbered one higher or one lower than Hal's.
2. Joe's favourite bird is the crow; his apartment number is one lower than that of Ike (who doesn't like robins).
3. The guilty person's apartment is not #3 (the number of the finch-lover's).
4. Gil is neither at apartment #1 nor the wren-lover.
Whodunit?
From the clues, we get the following possible positions
1 2 3 4 5
J I _ _ B this leads to "J I G H B" and "H J I G B" .
Thus, possible
Apt1 Hal Wren Apt2 Joe Crow Apt3 Ike Finch Apt4 Gil Robin
_ J I _ B This leads to "G J I H B" and "H J I G B" . The first is not possible, as G is not in Apt 1. Leaving us
Apt1 Joe Crow Apt2 Ike Wren Apt3 Hal Finch Apt4 Gil Robin
Thus, in either case, we get Gil-Robin-Apt4 , whereas J,I,H are different and their apartment no. can't be traced out. In either case, we have Gil Robin and in Apartment 4
Gil is the guilty person
