Funeral in Berlin features the same anonymous British agent as The Ipcress File. This is also the case for the three novels that follow it: Horse Under Water (1963), The Billion Dollar Brain (1966), and An Expensive Place to Die (1967), which are also spy novels.

Deighton has also written two books other than Funeral in Berlin that have to do with Berlin. Berlin Game (1983) is a spy novel which is the first volume of a trilogy featuring his agent Bernie Sampson as its protagonist. Winter: A Novel of a Berlin Family (1987) is a serious historical study of a well-to-do upper-middle-class family during the period 1920-1940.
