Maxwell is in his thirties and is an adrenaline junkie who thrives on stress. Professional and steely, Maxwell flew in mid 2009 from Hong Kong, where he worked in an emergency department, to replace Kip Denton as HOD of ED. He prefers to get the job done with a minimum of chit-chat, and his stern determination often puts him on the outer with his co-workers. Although blunt in his criticism of sloppy work practices, he can be charming when he chooses, and his brooding and romantic demeanour often draws attention from female staff. Coming from a lower socio-economic family, Maxwell has got a working-class chip on his shoulder, leading him to be hard on others who he believes have had it too easy.
