Pale Gray For Guilt5

Description for PALE GRAY FOR GUILT by John D MacDonald:

Travis McGee's old football buddy Tush Bannon is resisting pressure to sell off his floundering motel and marina to a group of influential movers and shakers. Then he's found dead. For a big man, Tush was a pussycat: devoted to his wife and three kids and always optimistic about his business -- even when things were at their worst. So even though his death is ruled a suicide, McGee suspects murder . . . and a vile conspiracy.

 
Tush Bannon was in the wrong spot at the wrong time. His measly plot of land just so happened to sit right in the middle of a rich parcel of five hundred riverfront acres that big-money real estate interests decided they simply must have.
 
It didn't matter that Tush was a nice guy with a family, or that he never knew he was dealing with a criminal element. They squashed him like a bug and walked away, counting their change. But one thing they never counted on: the gentle giant had a not-so-gentle friend in Travis McGee. And now he's going to make them pay.

This is #9 in A Travis McGee Novel.
