An eerie debut suspense novel that explores how little one man may know his own brother - and his own mind.

Each of the Maguire brothers has his own driving, single-minded obsession. For Jonathan it is his magnificent, talented, and desirable wife, Harriet. For Roger it is the elaborate universe he has constructed in a shed in their parents' garden, populated by millions of tiny insects. While Jonathan's pursuit of Harriet leads him to feelings of jealousy and anguish, Roger's immersion in the world he has created reveals a capability and talent that are absent from his everyday life.

Roger is known to all as a loving, protective, yet simple man, but the ever-growing complexity of the insect farm suggests that he is capable of far more than anyone believes. Following a series of strange and disturbing incidents, Jonathan begins to question every story he has ever been told about his brother - and if he has so completely misjudged Roger's mind, what else might he have overlooked about his family and himself?

The Insect Farm is a dramatic psychological thriller about the secrets we keep from those we love most and the extent to which the people closest to us are also the most unknowable. In his astounding debut, Stuart Prebble guides us through haunting twists and jolting discoveries as a startling picture emerges: One of the Maguire brothers is a killer, and the other has no idea.
