Our story this week is of a hardworking immigrant family, beavering away to improve the quality of life for Ealing. But first there’s hills made of rubble, classic comedy capers (we find out which world leader was their biggest fan) and the first incline lift in a tube station.

An experiment is underway at Paradise Fields, to see if Beavers can live in an urban setting. Since moving in last year the family have been coppicing trees, damming lakes, and filtering the water. We chat about why beavers were hunted to extinction in Britain, their extraordinarily useful fur and secretions, and how they are making a comeback.

We're still on an airfield this week. But it's all about the woman wielding the tools, keeping the planes aloft. It's 1941 and Lilian Bader is one of the first women to qualify as an instrument repairer. Her Barbadian father had served in the Navy, her husband drove tanks, her son flew helicopters. Across the generations her family served across the forces, and gave back more than they received. Lilian not only broke barriers as a woman of colour, she campaigned to remember the contribution made from across the commonwealth. Her unit were the first women in the WAAF to be given overalls rather than wearing skirts. Overalls that hang on the Women of World War two memorial in Whitehall. The uniforms and clothes adopted by women to commemorate all those who served, military and civilian.

Plaster wedding cakes, Pilots of the Caribbean and Who wants to be a millionaire? Plus Christmas trees, singing and an Easter egg. What's that you say Ben? BONG.

Mayday, M'aidez! I'm worried that Alex is turning to a life of crime!

Croydon: The international airport of London in the golden age of glamorous travel. Even the cargo was golden, and enticing. And this week we're learning why you should organise your own getaway car. Plus a superstar kidnapping caper. It's all go. Just as well Alex has had a relaxing holiday. No, I'm not jealous at all, I've been living it up in London with Bert.

We are slightly overexcited this week, as we're chatting with comedian and writer Eleanor Morton. Her fabulous book of lessons from historical women features many of our favourite women. And a host of, maybe, less familiar ones. From mountaineering and marathons to creating familiar music and much loved characters, we're casting the net wide this week. Who slapped who, and why? Who found adventure in the most dangerous of journeys? How does hiding in a cupboard help anyone?

Plus ghosts, tour guiding, the month of Edinburgh, and another potential podcast outing.

No animals were harmed in the making of this episode, although Rusty does join in.

We're taking a stroll through the medical powerhouse that is south Camden and focussing on Elizabeth Garrett Anderson. She's been on the fringes of many an episode - her sister and her daughter have already featured, now she gets the limelight. And boy does she deserve it. She overcame hurdles and jumped through loopholes, even learning another language in her fight to become the first female Dr to practise (while presenting as a woman) in the UK. Her co-founders of the London School of Medicine for Women, were equally determined, playing the establishment at their own game to learn their skills. Inspiring women whose legacy still lurks along the Euston Rd.

Plus a miniature distillery in Scotland. Cheers!

In a new guessing game Alex tries to pick the material chosen to sculpt the Prince of Wales. 100 years ago the crowds were gathering in Wembley for the extraordinary spectacle that was the British Empire Exhibition. A showcase for trade, manufacturing and, it turns out, people. Problematic? Just a tad.

But there was a miniature railway, a palace of engineering, a palace of art including the teeny tiny wine bottles in Queen Mary's Dolls House. And a regular display of destruction of the House of Commons. What's not to like?

When the empire was at it's height, but with the cracks beginning to show, an exhibition was bound to be both brilliant and disturbing. Join visitors John Betjeman and Virginia Woolf as we explore the exhibition together.

Calling all penny farthing enthusiasts, we need answers! New records have been set, and we want to know more.

Alex takes a dive into the Thames this week. Not the modern Thames, oh no, she's bravely gone back to 1858, the year of the Great Stink. What's that got to do with Bexley? The Crossness pumping station, that's what. An important part of Bazalgette's solution, his new improved sewage system, to transport the poop of London out the East. A very functional building then, presumably. Wait, have you met the Victorians?

And will our funky theme tune be hitting the charts or clubs any time soon?

We're very excited about our guest this week. With a suitably seasonally episode. What do we think about Spiritualism? Are mediums in contact with those who have passed. Doris Stokes held audiences enthralled, was it all smoke and mirrors? But how did she know about the money?

There's relocated bodies, fancy tombs, and a Bermuda Triangle in Blackheath. So that's how the highwayman disappeared.

This'll set you up nicely for Halloween. Sleep tight.

Did I mention the special guest?

Get your buzzers ready. We get competitive this week. Can you beat Alex in spotting the links to past episodes? Who'd have thought that Gladdie Park could be so well connected? And just around the corner was a unassuming building with a big story to hide. Partly the underground bunker, and partly their contribution to code breaking in WW2. Bletchley Park was the main centre for British codebreaking. Telecoms engineer Tommy Flowers and his team at Dollis Hill provided the equipment to break the most secret of all the codes. The Lorenz code of the Gerheimschreiber machines used by German high command. And if anyone doesn't know what Taskmaster is, where have you been?

You might not know her name but there's a decent chance you know her face. Fanny Eaton worked as a model for the Royal Academy and painters of the Pre-Raphaelite movement. Was she chosen for her beauty or seen as an exotic other? Alex goes in search of the beautiful Mrs Eaton. Possibly the most seen woman of colour in Victorian Britain.
