My Crazy Cousin Courtney Returns Again by Judi Miller, 1995.
Courtney is back in New York with her cousin Cathy and living her dream of becoming an actress! Courtney has landed a part in a movie called The Laundry Bag Murder (see the first book in the series for that explanation). With Courtney’s new professional responsibilities, Cathy hopes that this visit will be quieter than their last ones, but no such luck. Excitement follows Courtney wherever she goes, and if things aren’t exciting enough to suit her, she knows how to stir them up!
When Cathy and Courtney go to the Central Park Zoo to try out Courtney’s new video camera, Courtney ends up turning the expedition into a vampire hunt that ends up catching a criminal. When they go to see a friend’s rock band perform at a bar, Courtney turns a barroom brawl into a hug-in.
Courtney is also giving Cathy relationship advice. Cathy and Frank are boyfriend and girlfriend now, but both of them are pretty shy. Too shy to even go on a real date. Courtney says that maybe Cathy should act a little helpless to bring out Frank’s protective instincts and to get his attention. She says that Cathy should tell Frank that she thinks someone might be following her around (it’s not a lie if Cathy isn’t sure). That way, Frank will want to spend more time with her to look after her.
With some reservations, Cathy does tell Frank someone may be following her, which does get Frank’s attention. Then, to Cathy’s surprise, she actually does notice someone following her around. At first, she suspects that Courtney got another actress to follow her for awhile to make her story to Frank true, but it turns out, that’s not the case at all. Who is that mysterious woman in the sunglasses and what does she want?
There is another book in the series which I don’t have and haven’t read called My Crazy Cousin Courtney Gets Crazier. Courtney ends up going to school in New York with Cathy because she lands a role in another movie which will be shooting there during the fall.
