Another rollicking good yarn in the recent series of spinoff books about the life of Alastair Lethbridge-Stewart between the events of The Web of Fear and The Invasion. Peel is an old hand at this, having written the very first in the Virgin New Adventures series of spinoffs, almost thirty years ago. This story invokes Triffids, The Seeds of Doom and Fury from the Deep and boils up the elements to make a Brigadier story that is derivative but great fun. Continuing to enjoy this series. (Reference also to the DS9 pesticide from Planet of Giants.)
