For example, I did not know that Wells attended free lectures on socialism at Kelmscott House. I knew he was an early enthusiast of miniature wargames - I have a copy of Little Wars - and I also have the two volume set of his compact Outline of History, which I sadly admit I have not read as yet.
One interesting side note - it may be remembered that Voysey usually placed a signature heart motif on the door of every home he designed, but Wells reportedly did not want a heart, so the heart was replaced by a spade motif - thus the name. The house is now utilized as a nursing home.
