Call in the elite five man team that's attached to London's Metropolitan Police.
The Special Duty Investigation Unit.
Three cases. Five Men. Three Times Five!
The first adventure for the SDIU. It's 1970. London has stopped swinging and villainy is all around.
There's the loss of a prototype weapon, a security job in a Stately Home that's supposedly haunted and a murder case that becomes personal.
These are special cases.
They need a special touch.
They need the SDIU!
