the location of moore's grave is not known. his grandson, john, said: "the odd thing is that my father was such a good story-teller but he couldn't or wouldn't tell me where my grandfather was buried. it was if there was some unfinished business, some sort of mix-up, something i never understood. it's a mystery." moore believes the site may be near the welsh harp reservoir – also known as brent reservoir – in north london.
