This was a short story padded to the gills to make it book length. That much becomes obvious midway through the book, when Matheson constantly repeats the same tired thoughts of the love-sick protagonist -- namely, that he loves and needs the actress Elise. Over and over again we are reminded of this, until I wanted to hurl the book across the room and shout, "Yes! I KNOW IT!" The love story aspect required way too much suspension of disbelief, and was far too cloying. I was practically choking on the endless dialogue and thoughts of the two lovers expressing their undying love for one another -- this after meeting approximately 12 hours earlier.
If there was a redeeming factor, it came at the end, which was touching, and maybe even explains some of the unrealistic behavior throughout the book. But I don't think two nicely written pages at the end of the book justifies two-hundred-and-seventy pages of tiresome story. It would have made a much better short story; it would have been tighter, less tedious.
