The episode begins with a scene at the Pennebaker Club back in the ‘40s, where Castle is a detective cop, and Dr. Parish the jazz singer. He loves the music, and lets on to the bartender that he would need help for a date. The picture he shows him is none other than the woman he is looking at. He turns around, and finds a woman – the one who looks exactly like Beckett, but all fashioned up in a 1940s style. But that is all till then. Back to reality, Castle and Beckett are at the crime scene, where Stan Banks has been murdered. Although Castle is overflowing with stories from the ‘40s, Beckett reminds him that the only story they need now is about the victim. Stan is dead, which is news to the manager of the club – who doesn’t know what is to be done with the room in which he stayed. ..

Episode Goofs
The 1947 calendar we see in the background when Joe is getting roughed up is all wrong. First of all, it starts on a Monday and has 31 days so it has to be October. The double murder occurred on June 24. Earlier and June has only 30 days. Just the wrong page, you say?? Ah, but the month only has 3 phases of the moon and they are on the 10th, 19th, and 30th. The spacing is too great and there is never only 3 phases in a month. So this calendar month was created without any research.
