Needless to say, the yuppies found real estate agents, and the next thing you knew, old housing projects became million-dollar waterfront condos, and fourth-generation triple-deckers were sold to developers for five times the money anyone thought they’d ever bring.

The community became both more and less. Different economics and ethnicities. Same great parks and tree-lined streets. Added some coffee bars. Kept the Irish pubs. More upwardly mobile professionals. Still a lot of families and kids. Good place to live, if you’d bought in before the prices went nuts.

D.D. followed her GPS navigator to the address provided by Detective Miller. She found herself close to the water at a quaint little brown-and-cream painted bungalow with a postage-stamp lawn and a nude maple tree. She had two thoughts at once: Someone had built a bungalow in Boston? And two, Detective Miller was good. He was five and a half hours into a call out, and thus far, no ribbons of crime-scene tape, no parking lot of police cruisers, and better yet, no long lines of media vans. House appeared quiet, street appeared quiet. The proverbial calm before the storm.

D.D. drove around the block three times before finally parking several streets down. If Miller had managed this long without advertising, she wasn’t gonna give the game away.

Walking back, hands fisted in her front pockets, shoulders hunched for warmth, she discovered Miller standing in the front yard, waiting for her. He was smaller than she expected, with thinning brown hair and a 1970s mustache. He looked like the kind of cop who would make an excellent undercover officer—so nondescript no one would notice him, let alone realize he was eavesdropping on important conversations. He also had the pale complexion of a man who spent most of his time under fluorescent lights. Desk jockey, D.D. thought, and immediately reserved judgment.

Miller crossed the lawn and fell in step beside her. He kept walking, so she did, too. Sometimes, policing involved a bit of acting. Today, apparently, they were playing the role of a couple out for a morning stroll. Miller’s rumpled brown suit was a bit formal for the part, but D.D., in her slim-fitted jeans and leather jacket, looked dynamite.
