The story for this adaptation project comes from two Douglas Adams novels: Dirk Gently’s Holistic Detective Agency and The Long Dark Tea-Time of the Soul. Wood’s character serves as an assistant to the titular sleuth. The premiere episode will air in Fall 2016.
Here’s more from Deadline: “Todd does not consider himself a sidekick. He is just flat-out better than Dirk at a lot of things. He always attempts to solve matters with the fewest steps possible; despite being a compassionate, sweet, smarter-than-average man with biting wit, Todd often finds himself at the intersection of morally gray crossroads. Thus, his bad habits of lying and stealing have dire consequences that he can’t put off forever, even though he tries.” (via A.V. Club)
