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. ( )
