SUSIE’S CARIBBEAN CAFÉ is a mood changer in the best possible way. The walls are yellow, the calypso music is live, the food is hot, and the beer is cold. Susie’s is also the unofficial clubhouse of our gang of four, branded the Women’s Murder Club by our friend, girl reporter Cindy Thomas.

I desperately needed an hour at Susie’s. Conklin and I had spent the day looking for a newborn baby. We’d walked with cadaver dogs, checked in with divers at the edge of Lake Merced, and made an all-day, fruitless canvass of houses in the area, with Avis Richardson’s photo in hand, asking, “Have you seen this girl?”

Then, ten minutes ago, a stunning call had come in to Jacobi. Avis Richardson had turned up behind the locked doors of a schoolmate’s parents’ apartment on Russian Hill. These “do-gooders” were keeping Avis away from the cops until her parents could arrive from New Zealand. So Avis had been located, but we still had no leads on her baby, who was either missing or dead.

Probably both.

Claire and I drove to Susie’s together in my car and parked in a miraculously empty spot on Jackson Street near the corner of Montgomery. We came through the door into the lilting beat of steel drums and laughter, and waved to casual friends. We passed the bar and took the narrow and aromatic aisle past the kitchen to the cozy back room where Yuki was already holding down our booth.

Lorraine called out, “Hey, y’all,” and brought over a frosty pitcher of beer, along with Yuki’s watermelon margarita. Yuki cannot hold her liquor, but that doesn’t stop her from drinking it.

I slid into the banquette next to Yuki, while Claire took the other side of the booth. Yuki lifted her glass of pink liquid mind-bender and took a slug.

“Sip it!” we shouted to her in unison.
