Have just finished Express Big Monday Xword and Herculis. A flash of inspiration and a dash of google! Now have gk withdrawl symptons until Sat. Are there any other gk xwords the rest of the week?
The Financial Times has a GK xword on a Saturday - called Polymath. You have until the following Wedneday to complete it - 10 days - so you'd have plenty of time even if you only started it after you'd finished the others.
