Why was Turnbull killed?
Hint 1 of 6:
Travis was the Egyptian correspondant for The Times.
Hint 2 of 6:
So I'm sure that he wrote all of the articles about egyptology.
Hint 3 of 6:
He was also a nut (both a big fan and an insane person) about Egyptian
history, as you saw when you went to talk to him.
Hint 4 of 6:
Look in The Times to see if he wrote anything controversial about
egyptologists.
Hint 5 of 6:
There's an article at the top of page 2 of the August 17, 1888 issue.
Hint 6 of 6:
It happens to be about Turnbull. Travis was highly critical of him.
