Bikinis and budgie-smugglers at the ready, as the 25th episode of I'll Explain Later accompanies your summer break with another trio of tales!

Why have one when you can have two? A duo beating down on them, can Tom Baker and Louise 'Leela' Jameson ride out the heat and avoid the taxman in 1977 yarn The Sun Makers?

Oh no, it's clouded over! A typical British summer explored in harrowing depth over New Who Season 4 two-parter The Sontaran Stratagem / The Poison Sky.

And the Fifth Doctor and chums discover you can't sidestep bleedin' foreigners even on a staycation, encountering a pas probable foe in knightly nemesis Sir Gilles Estram. Lutes ahoy for The King's Demons!

Along the way, Matt worries about role models, Jim sings along and John muses on 23 years of hurt.
