Mortimer Fitzroy is a soul guide. Soul guides go to earth to pick up the souls of deceased people. When he's sent down to collect the souls of a few people who are about to die there is a lot more waiting for him than just a routine pick-up. His customers are not the easiest ones to deal with and finding a good place for them in the afterlife also proves a challenge. When Mortimer is facing matters of the not so dead heart, things become even more complicated.
