The Sign of Four

Having had such a lovely time with Partner watching The Hound of the Baskervilles, I was interested to see if there were any other Richardson Sherlock Holmes movies and was elated to discover that a version of The Sign of Four had also been made.

Famous detective and his partner Doctor Watson are hired by a young woman named Mary Morstan to investigate the recent death of her father’s friend from the army as well as the mysterious letter she received along with the Great Mogul, the second largest diamond in the world. What starts as an innocent mystery of a strange letter sent, soon turns immeasurably sinister with the renowned duo becoming immersed in a plot of murder and revenge.

The Sign of Four takes on a little more of a macabre edge than The Hound of the Baskervilles but nevertheless proves to be another enjoyable adaptation of a classic literary thriller. A timeless race against the clock to find a killer on the loose, the excitement of TSOF comes from the known human aspect of the plot rather than the supernatural course that HOFB travels.

Ian Richardson continues to be charming with a little more of an added heroic streak and a fiercer determination that colours some of the more memorable and action-packed scenes within the climactic third act. David Healy plays a lovestruck Watson adorably: slightly flustered, but mostly, sweet, sincere, and sometimes even cool (well, as cool as Watson can get).

The ominous settings of elaborate mansions, dust-filled attics, and carnival fairgrounds are shot in ways that nicely heighten the tension and the sinister and macabre elements of the plot, and the climactic final confrontation, while shot in brilliant daylight in an unlikely and constrictive location, is very memorable. The drama of the plot is also beefed up with the use of montage that conveys the passing of time and teasingly hints that there is a chance that the trail to the killer might even go cold.

A different story and thus, a different vibe of film, The Sign of Four is still an exciting and enjoyable thriller filled with mystery, action, romance, and gore. It felt a little more serious than Hound of the Baskervilles, but still served us perfectly for a cosy Friday night in.
