The Victim



Mike is the victim.

If Mike's sister and Jack's sister are the same person, then (a) reads "Lily argued exactly once with (Mike or Jack)" and (b) reads "Lily argued twice with (the same Mike or Jack)". These two statements contradict each other. Therefore Mike's sister must be different from Jack's sister.
If this is the case then there are two possibilities:

1) Jack and Carol are brother and sister. Mike and Lily are brother and sister. Jack is married to Lily and Mike is married to Carol. If this is the case, then (a) reads "Carol argued once with Mike" and (b) reads "Lily argued twice with herself", leaving Jack dead. Since Lily did not likely argue with herself, this is not the solution.

2) Jack and Lily are brother and sister. Mike and Carol are brother and sister. Jack is married to Carol and Lily is married to Mike. If this is the case, then (a) reads "Lily argued once with Jack" and (b) reads "Carol argued twice with Lily", leaving Mike dead. Since there are no contradictions, this is the solution.

Suicidal Monks

  If there is only one monk with red eyes, then he sees all the others are brown-eyed, so he must be the red-eyed one. He kills himself the first night. If there are two monks with red eyes, then each sees one monk with red eyes and reasons that if this other monk is the only monk with red eyes, he will kill himself the first night. Neither monk kills himself the first night, so they each reason that they must have red eyes too. Both kill themselves the second night. If there are three, each expects the other two to commit suicide the second night. This doesn't happen, so each deducts that he must be a third, and the suicides happen the third night. Extends to four, five, etc. If the suicides happened n midnights after the tourist's remark, then there are n monks with red eyes.
