YAY! I am so happy about this!
He’s already done a map for Rivers of London (if I have failed to link it before, here it is again: https://maps.google.co.uk/maps/ms?msa=0&msid=200258044548208777222.0004d430a51327a17fc3f&hl=en&ie=UTF8&t=m&source=embed&ll=51.523911,-0.113983&spn=0.102533,0.219727&z=12) and I have just discovered on his blog that he has done one for his second book, Moon Over SoHo: https://maps.google.co.uk/maps/ms?msa=0&msid=200258044548208777222.0004ddfd3439b284b1333&hl=en&ie=UTF8&t=m&ll=51.483093,-0.111237&spn=0.410502,0.878906&z=10&source=embed.
Also, whilst reading his blog, I have discovered that Rivers of London COULD be coming to television! If it does come to TV, I cannot wait!
Sorry, I could not wait to post about this.
