Git Sync Murder by Michael Warren Lucas

Murder on the Sysadmin Express

After accidentally solving two murders, Dale Whitehead hungers to stay in his apartment, hack virtual memory stacks, and forget the whole thing. Instead, his boss sends him to a technology/sci-fi convention in Detroit. He plans to endure his stint at the vendor table, stumble through his presentation, and escape anonymously.

A dead body ruins everything.

Dale finds himself battling liquid nitrogen ice cream, balky network addressing schemes, the Chaos Machine, and his own reputation, while the corpses pile up.

"Wait to see if it happens again:" Great for troubleshooting IPv6 multicast over wireless. Not so much for murder.
