The Time Police do not have problems. They have challenges. Idiots who want to change history have always proved 'challenging'. But now temporal tourism is on the rise - highly illegal but highly lucrative. If you're prepared to take the risk. To face down this threat the Time Police will despatch their toughest undercover agents. Which is fine until the unthinkable happens. Replacements are needed fast, and who better than three young officers who don't even look the part?

You know what they say. Hope for the best. But plan for the worst. Catch up with the tea-soaked disaster magnets in their latest madcap adventure as they hurtle their way around history.... 

It's Christmas at St Mary's and time for the traditional illicit jump. Except this one is perfectly legal. It's Major Guthrie's last jump. To the Battle of Bannockburn, no less. An important moment in history for two nations - one that warrants everyone's full attention. But Max soon finds herself grappling with a near-lethal game of pooh sticks, another avian incursion and two turbulent teenagers intent on piloting their own illegal jump. And that's all before they even get near 14th-century Scotland. For this is St Mary's, and nothing is ever simple.

It's Christmas time again, and all is not well at Frogmorton Farm. Jenny and Russell's daughter, Joy, is growing up. Not quickly enough as far as she's concerned but far too quickly according to Russell. Father and daughter are at odds, and suddenly the outlook is very dark indeed. That is until Thomas comes to the rescue. A Frogmorton Farm short.

Miss Marple meets Oscar Wilde in this new series of cosy mysteries set in the picturesque Cotswolds village of Bunburry. In "Sheep Secrets", the picturesque village of Bunburry is basking in midsummer sunshine when a shepherd finds a body in a nearby quarry. The deceased was taking part in an outdoor survival training course run by Neil Walker, friend of Constable Emma Hollis. The death seems a tragic accident, but Emma insists on amateur sleuth Alfie McAlister joining the course to save Neil's good name.

Have you ever wondered what would happen if Max's husband met Max's father? What would Leon do? They're normally a fairly amiable bunch, but this is the story of what to expect if St Mary's doesn't like someone. As in, really doesn't like someone. Warning: contains a unit-wide criminal enterprise, a great deal of illegal activity and a sad misuse of public resources. All the things a father will do to protect his family. It is also a story of revenge. Because this is payback - St Mary's style. Includes bonus St Mary's escapades 'Desiccated Water' and 'Markham and the Anal Probing'.

Max, Leon and Matthew - together at last for Christmas at St Mary's, a time of conspicuous consumption, riotous misbehaviour and the traditional illegal Christmas jump. And this time it's intergenerational. Donning her unfamiliar mother hat, Max takes Matthew back to 19th-century London, where they plan to deliver a parcel of Christmas cheer to his former friends but find themselves confronting the terrifying Old Ma Scrope in the process.

Follow the disaster magnets of St Mary's as they hurtle around history! The ninth book in The Chronicles of St Mary's Series collects the best-selling short stories in audio for the first time.

They say you shouldn't push your luck. Max gives her own luck a massive shove every day - and it's only a matter of time until luck pushes back.... January, 1536 - the day of Henry VIII's infamous jousting accident. Historians from St Mary's are there in force, recording and documenting. And arguing - obviously. A chance meeting between Max and the Time Police leads to a plan of action. And it's one that will have very serious consequences - especially for Max.

Behind the seemingly innocuous facade of St. Mary's Institute of Historical Research, a different kind of academic work is taking place. Just don't call it time travel - these historians investigate major historical events in contemporary time. And they aren't your harmless eccentrics either; a more accurate description, as they ricochet around history, might be unintentional disaster magnets.

Max is no stranger to taking matters into her own hands. Especially when she's had A Brilliant Idea. Yes, it will mean breaking a few rules, but - as Max always says - they're not her rules. Seconded to the Time Police to join in the hunt for the renegade Clive Ronan, Max is a long way from St Mary's. But life in the future does have its plus points - although not for long. A problem with the Time Map reveals chaos in the 16th century and the wrong Tudor queen on the throne. History has gone rogue, there's a St Mary's team right in the firing line and Max must step up.  

Max is back! New husband, new job, and a training regime that cannot fail - to go wrong! Take one interim chief training officer, add five recruits, mix with Joan of Arc, a baby mammoth, a duplicitous father of history, a bombed rat, Stone Age hunters, a couple of passing policemen who should have better things to do, and Dick the Turd. Stir well, bring to the boil – and wait for the bang! Join Max in the sixth instalment in the off-the-wall Chronicles of St Mary’s series."

I've done some stupid things in my time. I've been reckless. I've broken a few rules. But never before have I ruined so many lives or left such a trail of destruction behind me. As Max would be the first to admit, she's never been one for rules. They tend to happen to other people. But this time she's gone too far, and everyone is paying the price. Grounded until the end of time, how can she ever put things right?

History happens all around you. And, occasionally, to you. I could have been a bomb-disposal expert, or a volunteer for the Mars mission, or a firefighter, something safe and sensible. But, no, I had to be an historian. It began well. A successful assignment to 17th century Cambridge to meet Isaac Newton, and another to witness the historic events at The Gates of Grief. So far so good.
