Police Against Crime #6

Detective Dan Coffey is called to the Purple Parrot tavern in the dead of night to investigate the murder of its owner, Tony Quarto—a killing that appears to be a botched robbery until the tavern's trained parrot becomes the key to unraveling the case. As Coffey and his partner dig deeper, they discover the widow may be harboring a dangerous secret, and a mysterious bracelet inscribed with initials "R.B." points them toward a suspect with a violent past. Time is running out as the pieces of the puzzle snap into place.

Police Doctor Duncan Stuart witnesses the city's most daring bank robbery and is forced at gunpoint to operate on the gang leader—but before the criminals can silence him, Stuart improvises a brilliant escape using an unexpected application of medical technology. With his life and his colleague's hanging in the balance, the resourceful doctor must outwit his captors and get word to the authorities before it's too late.

Detective Dan Coffey stakes out a banker's estate after a blackmailer demands fifty thousand dollars or the man's daughter dies, but the case takes a dangerous turn when a suspect plants a poisoned needle trap that leaves Coffey racing against time. As handwriting analysis from the police lab connects multiple extortion notes to a single perpetrator, Coffey must track down the culprit—a cunning former actor named Erwin—before the toxin claims him. It's a tense game of cat and mouse where science, detective work, and a single identifying detail may be the only things standing between justice and a killer's escape.
