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 Sheffield, 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 section of 19th and 20th century Earth history in the TARDIS library is being constantly rewritten.
