The email landed in Jasper’s inbox with a thump. He'd sent off the DNA sample with a shrug, more out of boredom than curiosity. But the words on the screen… he started pacing, a nervous energy building inside him. He felt an urge to run, to shout, to do something utterly ridiculous.

Back inside, he began rearranging his entire apartment, then quickly deleted every single text from his phone. "Starting fresh! Literally!" he muttered.
