Dave Walker is not a ghost that walks or a Texas ranger. He is also not that other David Walker who writes comics. He has written all the same things as Robert Mackenzie, as befits writing partners. Together with Robert and Justin Greenwood, he is the co-creator of Image's COMPASS. He works a nondescript desk job. Having moved south his entire life, he lives in Sydney Australia, and is looking at Antarctic properties. He spends more time than he should on the bird site, arguing about comics as @professor_just.
