I wonder if anyone here could please help me to identify this fruit
before my friend, who has made jam out of it, poisens himself.
I think I have persuaded him to wait until we have some idea what it
is.

The bush is more than 15years old , possibly many decades old, in an
old garden near Nottingham.
Pictures are to be found he
