The publishing industry suddenly cares about whether its authors have integrity!

Though scribes Abigail Hart and Nancy Joyce Callahan weren't outed for passing off a fictional memoir, their gossip book Great Reservations: Two Concierges Dish about Outrageous Requests, Celebrity Encounters and Guests Behaving Badly at a Luxury Hotel may have violated confidentially agreements they signed with the Four Seasons Chicago when they worked there as concierges. And now their publisher is caving to fear.

The celebrity guest tell-all was supposed to hit bookstores on April 22; a PR campaign is already underway, and review copies have been mailed. But now that's all been canceled. Even the book's website, GreatReservations.com, is offline.

When the Four Seasons got wind of the coming tome, they notified Random House imprint Three Rivers Press that any material published would breach Hart and Callahan's privacy agreements. Except those two say they had been upfront about the confidentially contracts from the beginning.

And while the luxury hotel chain might want to protect its reputation of discretion, it's not like they were out to air the dirty laundry of celebs. Well, except John Cusack. Literally.

Although the authors drop lots of famous names in "Great Reservations," most of their comments were complimentary, or neutral at worst. Madonna is phobic about air-conditioning even on the hottest summer days. Demi Moore once fell for the "I just ran out of gas" scam on Rush Street, gave the con artist $20 and then sent someone from the hotel to check on his well-being.

Among those who fared poorly was popular Chicago actor John Cusack, who wasn't very popular with the Four Seasons staff, according to a review copy of the book received by the Tribune. Cusack once sent a "dishwasher-size cardboard box" full of dirty laundry to the concierge desk with instructions it was to be laundered, pressed and placed in the actor's room before his arrival. He also left his dirty clothes scattered around the room and had them shipped back to him. Cusack's behavior earned him the nickname "The Underwear Guy," Hart and Callahan wrote. [ChiTri]
