Rivers of London: Night Witch #2 (Titan, 2016)

Following a disastrous attempt to 'recruit' the witch, Vavara, a Russian oligarch turns his sights on Peter Grant and Thomas Nightingale -- two of London's finest policemen and its only wizards -- to help recover his daughter... apparently kidnapped by dark elemental forces. But for Peter and Nightingale, a dark betrayal from the past is about rear its ugly head... An all-new and original Rivers of London comic series, written by Ben Aaronovitch and Andrew Cartmel! Set between 'Foxglove Summer' and 'The Hanging Tree'.
