Yes the first issue of Peabody & D'Gorath is avaiable to download on ITunes now at this link
I believe it gives you an Epub file.
I do warn you however that it has butchered the double page spreads.
I would still recommend the PDF file which is also free which can be downloaded from the SLG Store
Thanks to anyone who downloads it!
Hear what people that aren't me are saying about Peabody and D'Gorath!
