Wisher – tome 4 Bowler Hat and Faery-Cane

Merlin is dying, cut down by Glee the Goblin’s bullets. And Nigel’s control over his powers is still insufficient to save him with a wish. One solution left: a vial of dragon blood, the only artifact that can revive the enchanter. The problem is that the vial is at MI-10 headquarters, part of its commander George Cross’s private collection. It’s time for the last of the Genies to go on the offensive.
