Dallas supports a strange and wonderful little industry of professional book reviewers. Not the ones who read a new best-seller and type 500 words of yay or nay. These folks perform the books. At churches, country clubs and women's luncheon groups, the book reviewers bring their tomes alive. More than 75 times this year Dr. Lurline Morrow, currently one of the most in-demand and most entertaining among the area's 40 to 50 professional reviewers, has been booked to do her one-woman/one-book act. She's packed the house at Highland Park United Methodist's popular speakers' series and now is busy all over Dallas (and as far away as Wyoming) presenting her new take on the biography Chanel: A Woman of Her Own (in the past she's done books on the scandal-ridden Gucci and Vanderbilt families). Her audience isn't expected to read the book or discuss it. Morrow admits that what she does is "purely for entertainment." But along with relating juicy facts about her subject, she's known to delve into the psychological profiles of the rich and famous. Part lecturer, part literary stand-up comic, Morrow's a star on the tea-sandwich circuit.
