After going through the big book of names and just throwing out some letters myself, I've come up with this list for Stri. Assuming Hussie doesn't go phallic on us and go with the most obvious choice (mysteries yo, private eye, his name may as well be Richard for all the mad detective stuff he could do... you know, provided he cared and didn't think it was a waste of time), we have quite a few options.
Likely Names: Dice, Dime, Dirk, Ding, Dito (play on Ditto), Dill, Dive, Dizz, Dink, Dion, Dine, Diss, Dial, Divs, Divy
Ironic Names: Dies, Dide, Didd, Digg, Digs, Dibs, Dist, Dien, Dims, Dimz, Diez, Digo, Dike, Dint, Dips, Dimo, Diya, Dizi, Dize, Diyo, Dini, Dimi, Dino, Divo, Dizo, Dilo, Ditt, Dile, Dipp
Not likely enough: Diza, Diya, Dixi, Diwa, Diwo, Diva, Divi, Didi, Diti, Dity, Dita, Diro, Dipo, Dior, Diop, Dinu, Dinh, Dima, Dika, Diku, Dila, Dipe, Dile
Just replace vowels where appropriate to come up with other ironic or (most likely) unlikely alternatives.
Of course, the most ironic alternatives (already mentioned in this topic as well) are:
1. The post was a typo and Di was a red herring, leaving us looking in the wrong part of the D list.
2. His name is going to be a typically female-only name so that everyone was looking in the wrong gender section.
