An interesting and imaginative film based upon the premise of Sherlock Holmes investigating the Jack the Ripper murders of 1888. Plummer and Mason make a good Holmes and Watson, amd there are a host of famous names who pop up in supporting roles. Loosely based upon Stephen Knight's book "Jack the Ripper-The Final Solution," Holmes and Watson find that there is much more to the Whitechapel atrocities than the random killings they appear to be, and those at the very top of the establishment are determined that the real motive behind the crimes remains secret. This is an exciting film, full of plot twists, though if you're familiar with Knight's book, you'll know what's coming. Nicely filmed and atmospheric. Similar to "Jack the Ripper," the 1988 made for TV mini-series starring Michael Caine.
