"Gloria and her best friends, Rose and Frank Galigani, are on vacation in the Big Apple. They plan to visit Matt's niece Lori Pizzano, a documentary filmmaker, and enjoy the holiday sights together: shopping on Fifth Avenue, dining in Little Italy, and honoring ancestors at Ellis Island, while Matt attends a conference with the NYPD. Unfortunately, Lori's documentary on ozone and environmental issues has deadly fallout. Gloria stumbles over the body of Lori's scheming camerawoman in a Times Square loft, and, once again, she is thrust into some dangerous sleuthing. With suspects ranging from a disapproving brother to a smooth-talking PR administrator to a self-protecting private eye, Gloria tracks a killer through an intricate landscape of colorful neighborhoods and famous landmarks. Taking us on a trip from the city's tallest building to its grand park, from its crowded ice rinks to a lonely corner of its two-million-square-foot museum, The Oxygen Murder is as exciting as a ride over New York City in a helium balloon."--Publisher's description.
