Publisher's summary
Tracking the anomaly that erased Hebe from history, the Doctor and Mel find an instability in Sheffield, 1864. Who is Mrs Virtue, the mysterious owner of the new steelworks? And can the Doctor untwist history before a natural disaster washes them all away...?

Part one
With the TARDIS damaged and thrown millennia off-course, the Doctor is unable to follow Patricia's time track and instead heads to Neepsend, the still point within a temporal anomaly stretching from 1864 to Hebe's time in the 21st century. The Doctor remembers a book concerning Samuel Harrison, a possible ancestor of Hebe's from the 19th century, but he and Mel find that the 19th and 20th century Earth history books in the TARDIS library are being constantly rewritten.

Patrick visits the newly-completed Patrician Works in search of better pay to support his wife, Mary, and their unborn child and argues with Mr Colton about the comparatively low wage on offer. Patricia, owning the business and calling herself Eugenia Virtue, is impressed and offers to pay him to bring together a gang to impede her competitors, but he is shocked upon seeing the cables of the time-suit entering her skin and only agrees when promised a better future.

The Doctor briefly moves forward in time without Mel noticing, after which they meet Mary and learn of an S. Harrison who writes for the Sheffield Times. The Doctor goes to Sheffield to investigate and again shifts into the future where he uses a security guard's mobile phone to research Harrison and realises that he has left Mel stuck in the path of the Great Flood, which will kill hundreds of people at Neepsend in the night.
