Chapter 13 – unlucky for some. Certainly its unlucky for Copperhead Bob as he was killed in a piece of pure aeronautic slapstick right at the end of the last chapter. The moral of the story is always look where you’re going when flying a plane.

This week – a seminar on false moustaches, using talc to grey the temples and how to limp convincingly from thirty paces.

Here we see Bob, seconds before his novelty demise.

He pukes in terror. That wasn’t in last week’s episode. Pity the poor family having a picnic in Superstition Peaks who gets drenched by Bob’s terror juice.

Bugger me – a parachute.

A Bob-less bang. Bob lives.

Dr Satan plays that game where you have to move the plane up and down to avoid clouds and rocks and stuff. We had it for the ZX Spectrum – it was ace.

Bob’s survival is confirmed. You can put the tissues away and stop comfort eating now – we have our hero. Heroes plural if you want to include the Copperhead.

Dr Satan realises that the control device has been removed from the plane and that the radio has been fixed. Dr Satan is appalled.

Hurrah – it’s the man from last week’s chapter whose life had become worthless. He’s found salvation. He can now speak to Flight 7 – hallelujah.

Dr Satan paces about a bit and then announces that the injuries suffered by the professor when he tried to remove the control device are a "most fortunate accident". He doesn’t go into details but permits himself a small cackle. How utterly evil. I suspect we’ll have another robot-breaks-into-hospital escapade. They’re always good in a crap way.

The pilot and the radio operator debrief one and other. The pilot says the ambulance has just taken Professor Williams away. The radio guy says he called the doctor and he has no ambulance. FAKE AMBULANCE~! Again.

"Maybe the DA sent it" says the pilot.

"I don’t think so" says the radio man. And with a face like that you can’t doubt his word. He’s like Bambi with a handkerchief.

Let’s welcome back Doctor Satan’s fake ambulance crew. They can also be seen serving ice cream at the sea side, marching up and down at a Foreign Legion fort and advertising Daz door to door in the Home Counties.

Speed arrives and asks to ride with them so he can get a statement from the Professor (they’ve remembered he’s a journalist). I don’t think this is a ruse – I think he really is blundering into a trap.

The ambulance driver is happy for Speed to join them.

"Hey – wait a minute…" says this artistically silhouetted late comer. Oh, if only he’d been on time. I suspect most of the rest of this episode would never have happened.

"Say – this ain’t the way to the hospital" says Speed. This is why he’s a celebrated journalist.

They rendezvous with Doctor Satan. I suddenly want to make a genuine guess – since Bob Copperhead isn’t in the car currently chasing the ambulance, he has to be in the back of the ambulance pretending to be Professor Williams.

Doctor Satan is pleased to meet Professor Williams. From the size and build I think I’m probably right.

Speed takes a subtle minute to photograph Doctor Satan’s licence plate. He could’ve written it down but he didn’t – that would be too obvious. Obviously memorising it was out of the question.

A car chase follows. I think Dr Satan is now on board the ambulance and Speed is in the car but I’m not sure. This serial’s entire outside shoot seems to have been done at night. Either that or I shouldn’t buy public domain prints off eBay.

The DA’s men want to shoot the ambulance. Of course they do. But they decide not to. Damn.

Ok, this is weird. The ambulance driver parked by the side of the road and ran off. The DA’s men spotted it, opened the door and found a bandaged figure inside. I’m confused.

The accent makes me think it’s Dr Satan under the mask but that would be absurd – why would he hand himself over to the authorities? Hang on – this has suddenly become intriguing. The serial has become interesting. My god.

At Scott Towers, Lois and "The Professor" look over the captured robot.

Bob arrives – bang goes my earlier theory – and is introduced to "The Professor". It’s odd that the real professor was blinded by the explosion and yet the only part of his face which doesn’t need the healing power of bandages is his eyes.

Just in case there was any doubt, look at those eyes.

Bob explains that, although Speed is a prisoner of Dr Satan, his camera was left behind and contains some important clue or other. No one has thus far mentioned how silly the back of "The Professor’s" head looks with that tuft of hair sticking out.

Bob gets news – the licence plate was a fake – registered to a hotel in Oyster Cove. Lois says it would be worth checking out. That wasn’t meant to be a hotel joke.

Meanwhile, at the hotel in Oyster Cove which Dr Satan carelessly used when registering a fake licence plate (WHAT~?) the telephone rings.

Dr Satan compounds his foolishness by phoning his secret hideout from Lois’s telephone. Even in the dark ages they could trace a call couldn’t they?

Bob arrives at the hotel and begins his magical transformation.

The Copperhead runs round the outside of the hotel for a bit before a fight breaks out.

He wins and soon rescues Speed and the Professor. But wait! We are forgetting that Bob doesn’t know that the fake Professor isn’t the real Professor.

They make their escape, unaware that a trap is waiting for them in the shape of a gun.

Bob inches his way along the wall. He’s as cautious as a man can be. This sequence takes ages and is incredibly dull – that’s how careful Bob is.

He then wanders out without a care in the world for some reason. He is shot.

We hear a thud. The end. Bob dies another moronic death. The man must have stupid juice running through his veins.
