Crossword Mysteries: Terminal Descent

After volunteering to participate in a crossword solving competition with a new supercomputer, crossword puzzle editor Tess Harper finds herself swept into the investigation of the bizarre murder of a tech CEO, who heads into an elevator, speaks to it, asking for the parking garage, and the elevator actually answers him. But instead of going down, it starts ascending. As it plummets he cries out to the interactive computer programming that runs the elevator, BB, but it hits the bottom.

Death by elevator makes a change from a stabbing or poisoning. This is a decent, if a little convoluted mystery that made it hard to keep with the characters, addition to the excellent Crossword Mystery starring cutie Lacey Chabert and Brennan Elliott.
