Anyone going to the Italian restaurant Osteria Antica Bologna in Battersea, south London, in the next few days would be well advised to order the pumpkin ravioli. That, or possibly the sea bream, or the minestrone. When they do, they might spare a moment to think about Victoria, whose life has gone from the chaos of addiction to being a whirlwind of energy, focus and commitment; or Robert, who through gardening has found something to live for; or Simon, who is justifiably proud of his spring cabbages.
