Book recommendations

[jonathan]

Hey gang, I was wondering if anybody had any assassination books they would recommend in particular. I've done moderate reading so far, so I really wouldn't want anything that strays too far off the beaten path, at least not for the time being. I'd rather take it step by step for now. Here's what I've already read...

American Brutus (twice)
Blood On the Moon (twice)
Manhunt (twice)
Alias Paine
They Have Killed Papa Dead
His Name is Still Mudd
We Saw Lincoln Shot
Bloody Crimes
Shall We Gather At The River

and yes, also Killing Lincoln (hangs head)

Thanks for any tips.
