What's the feminine form of wretch so wan and pale?

The October 30, 2007, issue of The Examiner, the San Francisco free handout of what was once a mighty Hearst-owned newspaper, features, on the Healthy Life page, an Associated Press article titled: "Work out at Work: New Product Combines Workstation, Treadmill."

Yes, the treadmill, once walked by British prisoners, including Oscar Wilde, for 6 hours/day (with five minute breaks every so often,) and now just anther piece of exercise equipment to jog on (at the gym) and to hang clothes on (at home,) is coming to work. No, not in the employer's gym -- in our cubicles. No more lounging around in chairs -- employees will walk (slowly) while trying to read a computer monitor, or while keyboarding and trying to read a computer monitor, or while talking on a phone wedged between shoulder and ear while keyboarding and trying to read a computer monitor, or while drinking something while talking on a phone wedged between shoulder while trying to read a computer monitor (and for all I know, keyboarding with one hand at the same time.) Assuming that becomes the standard workplace setup, will prisoners be expected to sit on chairs at workstations for hours at a stretch?

I strongly suspect that whoever is developing a treadmill workstation does not wear bifocals, much less trifocals. Or high heels.

The article suggests these websites: Steelcase Inc. (office furniture/design site -- uses the word Walkstation,) the Mayo Clinic, and True Fitness Technology (either a manufacturer or a vendor.)

This post's title is from what I thought was The Ballad of Reading Gaol, but isn't: so what is it from? I remember the line "In Reading town in Reading Gaol, there lies a wretch so wan and pale," but nothing further. That's not unusual for me: if the world of Fahrenheit 451 ever comes to pass, I'll join the book people and will be Bartlett's Quotations because all I can remember of poetry/drama are a few lines of any particular work. It's good to have an alternative career path, no?
