The Queen Mary University of London Master in Finance program is one of the many located in the city of London. It is a one year program requiring a dissertation to graduate. There are also optional classes that students can take in order to specialize or at least explore additional areas that they are interested in.
Like many universities in London and Europe, there are multiple MSF programs one can take, each offering a different specialization. I am linking to the main master in finance program, but you can check the others out once you go to the site.
You can also find a student review of the program here
