Boston Cream — Howard Shrier

David Fine is not the kind of guy to go missing. Or so his father tells PI Jonah Geller. A brilliant young surgeon-in-training, devout, devoted to his parents--last seen 2 weeks ago leaving the Boston hospital where he worked. Still recovering from a concussion, Jonah and partner Jenn Raudsepp soon find out that David fled for his life after a vicious Irish crime boss tried to abduct him. And that he's more likely dead than alive. Then Jenn joins the ranks of the missing, and Jonah needs help from former hit man Dante Ryan and two local wise guys as he races the clock to save her life, one step ahead of the Boston law.
