Grumpy Gumphrey Supersleuth (ZX Spectrum)

Developer Message
A message directed specifically toward someone can be seen at. Dear Chris Wood,we the Gremlin programmers hope that you approve of the logical structure of this Program,if you don't then PISS OFF! and hack into something else. We are preparing an especially hard hack proof program that will keep you busy for eons,or even longer! Vampires do live that long don't they?

This program was started on Microdrive,converted to a trashy TR disk drive that keeps CRASHING the source. Finally we gave up and bought a `6000 Pinnacle ,this amazing machine has a 12 Meg 68000 processor executing 3,000,000 instructions a second, so stick that up your Amstrad!!
