Teddy Bare, the Last of the Kennedy Clan.

“Teddy Bare,” which purports to tell the true story of Chappaquiddick, was first published in 1971 and has kept selling and selling. The publishers, Western Islands in Belmont, Mass., report that sales have increased markedly in the past few months, especially in California, where it “exploded” after former Los Angeles Mayor Sam Yorty mentioned it on his radio show in June. All told, the company said, 400,000 copies have been sold. Asked if it was selling largely in Massachusetts, Elaine Bechtel, an editorial assistant, replied, “It largely isn't selling in Massachusetts. That's Kennedy country.”
