We left the Copperhead – aka Bob Wayne – being molested by the least convincing robot in movie slash television history. The hulking tin brute was being carried by the robot and was in serious danger of being tossed off on the balcony. Sorry, that should read ‘tossed off the balcony’. I’m working with amateurs. Still, professionalism comes in the form of Professor Scott who unties himself and runs over to Dr Satan's control panel. He presses a button and saves the day.

Hooray for Professor Scott. You may think all he’s done is press a button but in actual fact he REBUILT the entire control mechanism because the old one DIDN’T HAVE a ‘Robot Off’ button.

Now that’s ingenuity.

Oh, it turns out it is all for naught as Bob is still thrown off the balcony.

And into the foamy brine. Or sea if you prefer.

Doctor Satan returns from wherever his trapdoor took him and regains control of the room. He reactivates his robot and uses it to threaten the recent Professor Scott.

Scott is taken to a room and sat down in a chair. Dr Satan has put on surgical gear. That can’t be good.

Scott makes a heroic speech about preferring to die than to help Dr Satan conquer America. Dr Satan is appalled.

He regains his wits eventually and does what any reasonable person would do – he gets a syringe and fills it with an evil potion.

The drug – which will paralyse Professor Scott’s will power – takes 15 minutes to work. To illustrate this we see a clock. Luckily, it is right on the hour – that’ll make it easier to work out when Professor Scott will fall under Dr Satan’s power.

Meanwhile, at Scott Towers, Lois gets a telephone call. It’s from the Copperhead. He brings good news.

We switch to Bob and find out the secret of how he maintains his secret identity – he puts a couple of fingers over the receiver and no one recognises his voice. Amazing.

She writes down the Copperhead’s phone number. Exeter 377. He has one heck of a commute each day.

Meanwhile, where evil is done, Scott has fallen under Dr Satan’s spell.

Scott gives up the secret of his control box – it’s Tonguite or something. I thought that was a slang term for female tennis players. There are no subtitles so I can’t check the spelling. Not that it matters – it doesn’t really exist.

It is a very rare mineral but Scott has an ample supply at his house in the care of his flat shoed, sensibly dressed secretary. Maybe he named it after her. Dr Satan and his chum scheme for a while and agree to send some men to relieve her of her metal.

It doesn’t take them long.

The goodies are taken down to the cellar where the Tonguite is kept. Luckily, Bob arrives and overhears their predicament. One of the men refers to the secretary as "sister" which does add fuel to the speculative fire.

He does what anyone would do – he dives through the window like the character he isn’t for legal reasons.

A fight breaks out.

The previously brave secretary takes her chance to scamper upstairs and leave everyone else to their damn fate.

The one baddie who stayed upstairs comes down to see what all the noise is about. He gets punched in the face for his trouble. So much for being neighbourly.

Bob loses.

The men run away.

But they don’t leave empty handed – Lois arrives home just as they are leaving and they decide to take her prisoner.

Back at Satan’s place, he gets what little tungite they were able to find before the fight broke out. At least we now have a spelling for it. So good of the Professor to paint names on his boxes.

Lois realises she’s been locked up with a telephone and decides to phone someone.

She calls the number the Copperhead gave her. At Bob’s flat, a thing flashes on his mantelpiece. He’s only been a superhero with a secret identity for a few days but he’s already sorted out the props.

He even keeps his phone in a secret little cupboard.

But it’s a trap – Dr Satan is listening to Lois’s call. He’s probably tracing it as we speak.

Nope – nothing so sophisticated. He simply cut her off and took over the call. He gives the Copperhead an address. 200 Oxford Street. Are you sure this is taking place in America?

Bob talks about the Copperhead in the third person even when he’s supposed to be the Copperhead. I think he thinks it makes him sound butch. It actually makes him sound like a superhero with a secretary. A butch secretary. Nudge nudge wink wink.

Bob goes to the address and quickly surrenders.

Dr Satan takes a few minutes out of his busy schedule to explain, in detail, exactly what will happen when the Copperhead turns up. OH THE IRONY~!

What a fiendish contraption – if the Copperhead doesn’t turn up by midnight, some gas pellets will be dropped into a vat of acid. These will release vapours which will kill Miss Scott. If he does show up, the door will be electrocuted, he’ll die and the pellets will kill Miss Scott anyway. It isn’t looking too good for Miss Scott.

Bob gets free, does another one of his overly dramatic dives and knocks out the henchman.

We then witness the miraculous transformation from Bob…

…into the Copperhead.

Dr Satan and his accomplice are worried – two minutes to midnight and no sign of trouble. They don’t seem concerned that the room will be full of poison in two minutes.

Exciting countdown music begins.

The Copperhead climbs up the fire escape to avoid the booby trapped door but is intercepted by evil.

Lois squirms the squirm of a woman who doesn’t want to be gassed.

The two men fall from the fire escape and are knocked out.

The pellets drop into the acid.

FUMES~!

She dies. Next week sounds good though so we’ll chalk her death up to experience.
