Closer, but not quite.

This route here is the network route for the 192.168.52.0 subnet (class C).
A host in the 192.168.42.0 network (like pc2) will not be reachable because
of the netmask of 255.255.255.0.  Either alter the netmask to 255.255.0.0
or put pc2 in pc1's network by setting its IP to something like
192.168.52.2.

These are just basic IP networking principles.  Unfortunately, I cannot
think of any good books on this issue, and the best I found in the HOWTOs
was this coverage in the Net-3 HOWTO:
