Lestrade and the Brigade

Book five in the Inspector Lestrade series. There is a new broom at Scotland Yard; Nimrod Frost. His first 'little' job for Lestrade is to investigate the reported appearance of a lion in Cornwall, a supposed savager of sheep and frightener of men. Hardly a task for an Inspector of the Criminal Investigations Department. Yet even as Lestrade questions a witness, a man is reported dead, horrifically mauled.
Having solved that case to his own satisfaction, Lestrade returns to London and to another suspicious death and then another . All old men who should have died quietly in their sleep. Is there a connection - is there a mass murderer at work? Lestrade's superiors discount his speculations and he finds himself suspended from duty, but that is a mere technicality to the doughty Inspector. He moves from workhouse to royal palace, from backstage at the Lyceum to regimental dinner in search of clues and enlightenment. When can his glory fade?
