By Steve Hodel. This is a fairly amateurish presentation from Hodel, who whatever else you think of him is a name in the field (the "also, by Steve Hodel [sic]" page, for starters). Alas, part of that name was made on what's considered crackpottery, and Hodel's "solving" of the 1938 murders in the (...endless) subtitle may be more of the same. Someone, unpinch a penny and buy a hyphen.
But there are those who find Hodel's wool-gathering fascinating, and for you folks, this paperback is brand-new from the warehouse.
