You’ll find this in Deep Navigation.
It seems that someone’s been leaking top secret information from a top secret facility in a different reality and a detective is sent to investigate. The only problem being that the only way to get there is to have his consciousness uploaded and sent by signal and then put into a new body at the other end: exactly like in Altered Carbon. But for some reason the detective finds himself re-sleeved into a bit cat’s body: hence the title Tiger, Burning.
Really good, Alastair at his best, as usual.
Next up in Alastair’s timeline will be Signal to Noise, from 2006.
