Dovercourt was located either in or in close proximity of Essex.

In 2065, Corley attempted to send a guarantee of safety to the Kaplan Minus that he would not be assassinated if he was to visit Dovercourt with Corley adding that he would act as the Kaplan's personal escort for its duration. However, the Kaplan died before it was received resulting in Agent Twenty One of the Universal Secret Service assuring Corley that the guarantee would be given to the new Kaplan instead.
