Some don't like it hot

Euh. Hot day in the City of London. Flushed from success at yesterday's correct call about clothing – wearing a heavy leather jacket on what turned out to be a dull, overcast day – genius here wore it again today with the result that I am a mobile sweatbox in multiple black layers. Everyone else in the City is pottering around in shirt sleeves or flimsy blouses, depending on the relevant gender.

Current count for Iceland postcards: seven.
