On the back cover of the large print book, the synopsis is correct but the book is listed as "A Seaside Knitters Society Mystery * Book 5". Goodreads lists it as Book 16. The author's website does not provide a number, but shows "The Wedding Shawl (May 2011, #5)" in the photo-listing of the Seaside Knitters series.
Summary
"The holidays are kicking off in style at Mayor Beatrice Scaglia's holiday party, where a crowd admires the mayor's new home and the celebrity chef catering the event. An additional treat for Ben and Nell Endicott at the festive affair is reconnecting with a college friend, Oliver Bishop. But before the partygoers can toast the festive season, the chef--and wife of the Endicotts' friend--is found dead beneath the mistletoe. Izzy, Birdie, Nell, and Cass must uncover the pattern to these mysteries to bring a murderer to justice--and keep Sea Harbor's holiday magic from vanishing into the winter air"-- Back cover.
