Any ideas on how to get a biro pen mark out of suede?

[ffswhatnow]

That's it really - got a lovely pale green suede handbag - use it for work - and I stupidly forgot to put the cap on/didn't look when putting it away. Result is a 3-4cm mark that I have no idea how to get rid of. Any ideas?

I've been reading the tips on here and hairspray seems to get biro out of most thins. You might them have a problem with a hairspray stain but surely that's easier to deal with than biro.
