Welcome to our most ambitious project yet - a 12 days of Christmas themed advent calendar, twelve episodes, each one releasing in the days running up to Christmas!

Today Mike, Jon, Danny and Alan escape from the first door of the advent calendar - the partridge in a pear tree!

Can they solve the enigma of the cooling elf? Or will they disrespect the departed and ignore the frantic quacking of a sad duck?

For some reason they recorded this one in a noisy Wetherspoons at St Pancras after doing a real escape room and having lots of beers. It felt like a good idea at the time.

Merry Christmas! If you'd like to spread a bit of cheer, why not get in touch via the twitters @TIER_podcast?
