Morrow's newest bestseller, Martha Stewart: Just Desserts, by Jerry Oppenheim, is not making its subject very happy. In fact, America's doyenne of domesticity has been calling some of the people (the author claims to have spoken with more than 400 of Martha's present and former friends, colleagues and family members) interviewed to express her displeasure. Oppenheim has visited eight cities, averaging six to eight interviews in each, and will do a 20-city satellite tour July 24. He figures that he has, to date, done about 100 phone interviews. First printing was 60,000 but the current in-print total is more than 100,000 after five trips to press. Both the National Enquirer and the Star ran three-part series-noteworthy because the two tabloids usually don't excerpt the same thing. In early July, Dave Letterman used the book in a top 10 list of revelations we didn't know about Martha Stewart (she made her first husband entirely out of twigs and bark; she once spent an afternoon in a hotel room with Frank Gifford rearranging furniture; and, the #1 revelation: her personal favorite recipe is for anatomically correct gingerbread men).
