The Check Mark killer is on the loose in Pittsburgh and Detective Daniel Hayes and his SAS team members are struggling to crack the case. The victims don’t appear to have anything in common other than the mysterious check mark messages left near the bodies, but the SAS team’s investigation is determined to find the killer before his next Friday killing day rolls around.
This is the second Daniel Hayes book I’ve read by Robert Germaux, having read Small Talk, which I loved. I was certainly not disappointed with One by One. This is another suspenseful, tasteful detective novel – no gratuitous sex or swearing here – just the way I like my detective novels.
I loved that the SAS team works so well together to solve the Check Mark killings. There’s none of that one-upmanship or friction among team members, which I find often bogs down other detective novels. The SAS members all have jobs to do and they do it well by working together.
As in Germaux’s other novels, his protagonist is quite the romantic. Daniel Hayes is an all around nice guy who treats everyone with respect and compassion – in other words, he’s an extremely likeable guy. I did find his love interest, Lauren, to be ever so slightly conceited, but it certainly didn’t ruin the story for me.
I’m happy that Robert Germaux is continuing to write his Daniel Hayes detective novels. I’m looking forward to the third book in the series. I highly recommend One by One!
