Hellhound On His Trail by Hampton Sides was a great book about the manhunt for James Earl Ray, the killer of Martin Luther King Jr. The book starts with the escape of a prisoner in April, 1967, one year before the assassination of King, and there's fascinating detail in it about Ray, his actions and the times.
Details about the 65 day manhunt included Ray going to Atlanta, his car being discovered there, then clothes of his being traced to a Los Angeles area dry cleaner, which led to the FBI discovering a fingerprint match that established his identity. After this, police found that he had spent time in Canada under an assumed name. Then Canadian authorities poured over passport applications, found that Ray went Europe and alerted authorities there. Even with that alert going out, Ray was only apprehended trying to leave London as the result of authorities noticing he had a second passport, cancelled due to misspelling in the name, and someone then connecting that he was a fugitive. Incredibly, after Ray was returned to America and sent to state prison for the murder of King, he escaped and was caught in the mountains after 54 hours on the run.
It's a remarkable story told with great detail by Sides and I enjoyed it at least as much as I did two other excellent reads from Sides, Ghost Soldiers, and In the Kingdom of Ice.
