Criss-Cross was the two hundred and fourth story in Big Finish's monthly range. It featured the Sixth Doctor and properly introduced companion Constance Clarke, who had previously appeared in The Sixth Doctor: The Last Adventure due to its earlier than previously scheduled release. This was meant to be Constance's audio debut.

Publisher's summary

Bletchley Park. Britain's most secret weapon in the Second World War.

Inside draughty huts, the earliest computers clatter day and night, decoding enemy transmissions and revealing intelligence crucial to the country's defence. Leading WREN Mrs Constance Clarke directs her charges to provide vital assistance to the boffins stationed in the Manor House. But a recent arrival among the code-breakers, the mysterious Dr Smith, has attracted the attention of MI5's spycatchers...

Over in mainland Europe, Nazi agents are briefed, covert operations planned, and a German submarine embarks on a very secret mission.

As encrypted radio waves criss-cross the planet, unearthly forces stir. And when certain cyphers are cracked, something will emerge to threaten all humanity, regardless of allegiance...

Until now...
