The Fall and Rise of Henry Milch

In the third book of the Wyandot County Mystery series, Henry is very excited: He's just bought a car-and his old roommate in Los Angeles wants to get an apartment with him.
But then, when he stops in at his doctor's to pick up an Oxy prescription (he's titrating down, honest), he accidentally trips and falls on the doctor's corpse. That leads to his being a person of interest in the murder. Now he has to clear his name before he can even think about returning to LA.
As he does, he has to contend with a friendly private eye from Grand Rapids, a long line at his local drug dealer's, an over-crowded book club-and one very unexpected, very large surprise.
