The Fall Guy by Claire McNab

Milton Ryce was a man whose lifelong dedication to humiliating others through cruel practical jokes left him with few genuine allies. Despite his vast wealth and purchased influence, his abrasive personality created a vacuum of sympathy when a skydiving excursion resulted in his calculated murder. Detective Inspector Carol Ashton is tasked with navigating a crowded field of suspects, many of whom are Milton's own family members eager to see him gone. The investigation takes a bizarre turn when Milton’s son, Ted, executes a disturbing stunt at the funeral, drawing immediate police scrutiny. As the evidence against the young man mounts, Carol must determine if Ted is a cold-blooded killer or the final victim of a scheme designed to frame him as his father's ultimate 'fall guy.'
