Peter and three of his schoolmates were given an assignment to give an oral report on famous criminals in history. The four boys chose to report on famous real vampires, and each boy chose a different famous real vampire from history.

From the following clues, can you determine each boy's full name and chosen vampire, along with the order in which the four gave their reports?

1. Adam gave his report before the Adams boy but after the boy who reported on Peter Kurten, the famous Dusseldorf vampire.

2. Mark gave his report before the Peters boy, who gave his report before the report about John George Haigh, the famous vampire of London.

3. William did not give the last report; the Marks boy did not give the first report.

4. The first and last reports reviewed the lives of Elizabeth Bathory (the famous Hungarian blood countess) and Fritz Haarmann (the famous vampire of Hanover, Germany) but not necessarily in that order.

5. The Williams boy did not report on Elizabeth Bathory.






The last boy to give his report was not Adam (clue 1), Mark (clue 2) or William (clue 3), so it was Peter. The first to give his report was not the Adams boy (clue 1), the Peters boy (clue 2) or the Marks boy (clue 3), so it was the Williams boy. Consequently, Peter is not the Williams boy.

The second report given was not the report on J.G. Haigh (clue 2), E. Bathory or F. Haarmann (clue 4), so it was on Peter Kurten. The third report given was not the report on E. Bathory or F. Haarmann (clue 4), so it was on J.G. Haigh.

So far:

Report	First Name	Last Name	Subject
1		Williams
2			Peter Kurten
3			John G. Haigh
4	Peter

The Williams boy did not give the report on E. Bathory (clue 5), so he reported on F. Haarmann. By default, Peter reported on E. Bathory. By clue 1, Adam gave his report third, and the Adams boy reported fourth. By clue 2, the Peters boy reported second, and Mark reported first. By default, William reported second, and the Marks boy reported third.

To recap:

Report	First Name	Last Name	Subject
1	Mark	Williams	Fritz Haarmann
2	William	Peters	Peter Kurten
3	Adam	Marks	John G. Haigh
4	Peter	Adams	Elizabeth Bathory
