Ask the Right Question — Michael Z. Lewin

“A smoothly written private‐eye story” and Edgar Award Finalist: Indianapolis PI Albert Samson stirs up a wealthy family's secrets (The New York Times).
 
It's a slow afternoon for Indianapolis private detective Albert Samson. He's just awoken from an office doze when a new client walks in. Sixteen-year-old Eloise Crystal recently discovered that her blood type doesn't match either of her parents', and she wants Samson to find her biological father.
 
Skeptical, but one hundred dollars richer, Samson begins some preliminary digging into the past of one of the most respected family names in Indiana. What he unearths is the kind of dirt that makes people do desperate things -- and it thrusts him into a shifting world of lies, old money, and murderous secrets.
 
A beloved series by a Shamus Award�"winning author, Ask the Right Question introduces the smart-mouthed midwestern detective “who's always good, wry company” (Kirkus Reviews).
 
Ask the Right Question is the 1st book in the Albert Samson Mysteries, but you may enjoy reading the series in any order.
