When someone mentions the City of Cambridge you probably think of an
iconic building, its four corners stretching out of the once medieval
mud and into the arms of everlasting heaven, its white limestone
yearning into eternity... and without even knowing exactly what
ephemeral joys or permanent wonders the vision brings to mind, it s a
safe bet that the one thought which doesn t occur to you is that the
Chapel might not be there by Christmas. Theo (Theophilus Ambrose
Fitzwilliam Wedderburn to his friends) is a Junior Research Fellow in
Number Theory. Prompted by a supervisee to demonstrate how to trace the
provenance of bitcoins, Theo happens across a shocking revelation, with
embarrassing ramifications for the whole University. Meanwhile he is
being stalked unseen by someone from his childhood. To his annoyance,
Theo falls for a cheap con... and discovers a horror set not only to
rock the very seat of power itself but to change the face of Cambridge
and its beautifully iconic image for ever.
