Falling Angel -- William Hjortsberg

At first, I thought that this seemed like a typical noir-ish detective novel:

666 Fifth Avenue was an unhappy marriage of the International Style and our own home-grown tailfin technology.  It had gone up two years before between 52nd and 53rd streets: a million square feet of office space sheathed in embossed aluminum panels.  It looked like a forty-story cheese grater.  There was a waterfall in the lobby, but that didn't seem to help.

But then you meet Harry Angel's client:

Seated there in a custom-made blue pin-stripe suit with a blood-red rosebud in his lapel was a man who might have been anywhere between forty-five and sixty.  His hair was black and full, combed straight back on a high forehead, yet is square-cut goatee and pointed moustache were white as ermine.  He was tanned and elegant; his eyes a distant, etheral blue.  A tiny, inverted golden star gleamed on his maroon silk necktie. 

The client's name is Louis Cyphre; he wants Harry to find a man:

Cyphre stubbed out his cigar in the ashtray and toyed with the age-yellowed ivory holder.  It was carved in the shape of a coiled serpent with the head of a crowing rooster.  "Be patient with me, Mr. Angel.  I'm getting to the point, however circuitously.  I gave Johnny some help at the start of his career.  I was never his agent, but I was able to use my influence in his behalf.  In recognition of my assistance, which was considerable, we had a contract.  Certain collateral was involved.  This was to be forfeited in the event of his death.  I'm sorry that I can't be more explicit, but the terms of our agreement specified that the details remain confidential."

Do you see where it's going?  I did, but I didn't believe it until I checked the publication date: 1978.  Then I knew I wasn't imagining things.  Or at least, I thought that I knew that I wasn't imagining things.

Way fun.  And hey, there's a movie!  I had no idea!  And William Hjortsberg wrote the screenplay to Legend!  Yeah, Legend!  From back when Tom Cruise didn't suck!
