When Mildred Bauer is found dead, it's between her maid Maria and her granddaughter Laura as to who might've done her in - or could it have been Mildred herself, old and infirm, who had simply given up all hope of living?
This one is a bit of a frustrating watch, because it takes the tack of casting a whole lotta doubt on who exactly did it, right up until the very end - and even then it's hard to say. Some Law & Order episodes feature late-game twists that suggest the DA's office might be on the wrong track, and some feature devilish fiends who the lawfighters are 99% certain are actually guilty; this one just kind of spins you around the whole way, so your mileage may vary.
Great performance by Jan Miner as the victim's friend, one of her last. She's funny and down-to-earth - probably the episode's standout. And look out for a young Daniel Dae Kim as the medical examiner; his scenes are brief but he comes across as supremely friendly and charming, to the point where I was disappointed to find that this is his only L&O appearance.
