The door creaked open and the children tried to make sense of the scene before their eyes. They walked into what appeared to be a study of sorts. Shelves of books lined the walls, glass cabinets contained a strange array of mechanical devices on top of which were various pieces of lab equipment. A variety of electronics clicked and whirred while multicoloured LEDs flashed. A black leather chair was tucked under simple desk. It carried a computer, lampstand, an old letter writing slope, a discarded magazine and an inkwell. Three plain chairs sat facing the desk. The door closed behind the children. They turned around to find they were alone.

​

Curiosity got the better of the twins. James headed toward the cabinets and immediately spotted a type-writer-like machine of the sort they had discovered in the cache. Sarah was intrigued by the books. Such a strange collection. Amongst the myriad of maths and science books sat classic fiction penned by Jane Austen, maps, books on history...

​

“There’s some sort of logic-lock on this cabinet,” said James trying to free the contents using the coloured slides. “Thirteen of fifteen As are Bs; nine of fifteen As are Cs. So there must be at least… er... how many Cs that are Bs?” 

​

“Ah that’s easy,” replied Sarah. “But you should see this magazine. The whole thing is in code.”  She scrutinised the pages.  

​

Just then, a smile crossed James’ face as the logic puzzle lock fell to the floor; and Sarah simultaneously announced -

 

“I know where we are!”
