Murder, spies, mathematics and music - it's all in a day's work for
Phryne Fisher in her 20th adventure! An orchestral conductor has been
found dead and Detective Inspector Jack Robinson needs the delightfully
incisive and sophisticated Miss Fisher's assistance to enter a world in
which he is at sea. Hugh Tregennis, not much liked by anyone, has been
murdered in a most flamboyant mode by a killer with a point to prove.
But how many killers is Phryne really stalking? At the same time, the
dark curls, disdainful air and the lavender eyes of mathematician and
code-breaker Rupert Sheffield are taking Melbourne by storm. They've
certainly taken the heart of Phryne's old friend from the trenches of
WW1, John Wilson. Phryne recognises Sheffield as a man who attracts
danger and is determined to protect John from harm. With Mendelssohn's
'Elijah', memories of the Great War, and the science of deduction
ringing her head, Phryne's past must also play it's part as MI6 becomes
involved in the tangled web of murders.
