Solving things, uncovering an answer, is one of the joys of being human – just look at the vast numbers of us drawn to both murder mysteries and puzzles.
But there’s something that can be even more rewarding than finding the answer which is, after all, the objective of the puzzle or the end of the story. And that is something that you don’t even need to discover, an unannounced extra that has been hidden purely for the fun of it.
In video games and movies, these have long been known as Easter Eggs. (There is a legend that this arises from The Rocky Horror Picture Show where some of its very dedicated fans have spotted actual Easter Eggs rumoured to have been overlooked in an egg hunt organised by cast and crew – perhaps unlikely given the movie was filmed in the Autumn. It’s more commonly accepted the phrase arose from the game Atari where the developer hid a credit to his own name.)
For solvers of crosswords, these hidden messages abound – you might find one spelt out in an acrostic at the start of clues, in the letters round the edge of a completed grid, or in the words at the top and bottom, for example. Perhaps it’s unsurprising that for people who love playing with words – and whose cryptic setter names are themselves playfully hiding their true identity - they are a fairly common occurrence. Some setters have regular Ninas – such as Pangakupu who frequently hides words and messages in Māori in their puzzles. Well-known examples from the Guardian include a puzzle from the much-loved setter Araucaria, who revealed the news of his late-stage cancer to solvers in a series of clues. And in 2017 those who solved a puzzle by an apparently new setter called the Sphinx discovered they were in fact completing the same puzzle that featured in that evening’s episode of Inside No.9 – The Riddle of the Sphinx. The setter was one of the show’s creators, Steve Pemberton.
In the world of the cruciverbalist these hidden messages are called Ninas, named after the work of American caricaturist Al Hirschfield, who would hide his daughter’s name, Nina, in the lines of his drawings.
In Murder Most Cryptic, my debut novel combining murder mystery with cryptic clues, the protagonist is called Nina – an allusion for crossword fans to enjoy. And there are plenty of other Ninas for readers to find, if they wish to look for them.
In the crosswords that feature in the novel they are used to give additional information about what happened to the man who collapses and dies in Chapter One. These Ninas help the recovery group at the heart of the book begin to piece together what might have happened. But there are also clues from these crosswords at the head of each chapter, with the word that is the answer hidden somewhere in the chapter itself. These are not part of the plot, just something extra for the reader, a treasure hunt if they wish to take part in it.
One of my Ninas in Murder Most Cryptic is something I haven’t yet revealed – a message hidden in the names of all seven principal characters. I’d love to know if anyone thinks they’ve spotted it….
Readers of Murder Most Cryptic might also spot references – some more obvious than others – to other crime writers they enjoy. The books of some of my favourite authors appear and comments on a blog one of my characters writes gave some freedom to sneak in yet more allusions that readers may recognise.
This is something that authors who find their written work transferring to the screen may also indulge in - a moment of mingling among their own characters for that other type of Easter Egg, a cameo. Who spotted Mick Herron sitting alongside Diana Taverner during a funeral in the latest series of Slow Horses?
It’s a little treat, a surprise, something extra for a mystery lover.
For although a setter or writer can convey a huge range of messages hiding in plain sight, the vital thing about a Nina is that it is not necessary. The solver doesn’t need to spot it to complete the crossword, it’s simply there because it exercised the setter’s mind and they hope it will do the same for the the solver. It’s all just part of the game.
