She is staying indefinitely at the rural isolated estate of Ryman's widow, Danielle Ryman, on her invitation. There, Susan will have access to Henry's materials. Beyond Danielle, Carter the valet, and Lillianne the maid, the only other person living at the estate is Henry and Danielle's son, Georges Ryman. Georges is wheelchair-bound from an accident suffered six years ago, which ended what looked to be the start of a promising tennis career. Georges admits that he probably disappointed his parents by not being musically inclined like most people in their family.

Lesser Hammer film
21 November 2015 | by Wizard-8See all my reviews

Around this time, the type of movies that Hammer was most famous for were becoming out of style, so the studio desperately tried to tackle some other kind of movies, this being one of them. Few of these new efforts were successful financially or critically, and "Crescendo" was not an exception. There are two main problems with this movie. The first being that the movie unfolds at an extremely slow pace. In the first half hour of the movie, for example, pretty much nothing of significance happens. Eventually things do start to happen, but the movie not only still suffers from a glacial pace, there is the second problem with the movie. That being that the story is often head-scratching. It doesn't make a whole lot of sense, and even though the movie tries at the end to have a big surprise revelation, there are still plenty of unanswered questions as the end credits start to roll. I will say that the movie is decently produced, from the nice looking sets to the work with the camera, but that did little to stop me from starting to nod off long before the movie reached its end.
