"Where did you learn that?" Driscoll asked.

"Colm! He knew everything about insects. Near the end of his stay we had a mosquito problem at this pond. Real bad. Lazarus wanted to spray DDT, but Colm said it would kill the songbirds and other beneficial insects. He ordered a batch of dragonfly eggs, a variety from South America. Those dragonflies, they were like tigers! Each one gobbled up nine hundred mosquitoes a day. In a month, the mosquito problem was licked. That was Colm for you."

"Quite a guy."

"Yeah. Nobody else like him."

Etteridge's face grew somber. He became silent, staring into the darkness of the pond.

"Tell me, Mr. Etteridge, do you like it here?"

"They let me make the coffee." His face beamed. "It was Colm who showed me how to work the dispenser. He knew everything about the stuff. Did you know coffee was discovered in Ethiopia?"

"You learned that from Colm?"

"He talked about coffee all the time. Mr. Pierce, senior, was a coffee importer and a great dad to Colm."

"Did you know him?"

"Not too well, but I know Colm was close to his dad."

"Did his dad visit often?"

"He practically lived here. And Miss Langley was always pleased to see him."

"Who's Miss Langley?"

"Colm's nurse. It was Miss Langley that encouraged Colm to become a doctor. It sure made his dad happy. Boy, I sure miss her and those visits to her house."

"You went to her house?" This man was a wealth of information. Screw Lazarus and his obstinance. Driscoll's prayers had been answered.

"His dad would take us there. Miss Langley would make French pastries. We'd all sit at the kitchen table and eat them with hot chocolate, and then Colm and I would play Scrabble for the rest of the evening."

"And Colm's dad and Miss Langley?"

"They'd go into the bedroom and watch Ed Sullivan."

"I sure would like to have a talk with her. Does she still live in the same house?"

"I think so."

"Could you give me directions?"

Etteridge did.

Chapter 81.

The gingerbread cottage seemed more like the residence of an elf from Tolkien than a nurse in retirement. Driscoll found the doorbell. It was carved ivory, etched in the shape of a musical note. He depressed it. Chimes echoed, but his call went unanswered.

"Lookin' for old lady Langley?" a voice sounded.

Driscoll turned to find a small boy, no more than five or six. He was crouched on the slate steps of the house next door, sharing his lollipop with a Brittany spaniel.

"Is this her house?"

"Sure is."

"You think she'll be back soon?"

The youngster pointed to a small cemetery on a double-sized lot at the end of the block. "That's her over there, feedin' the birds."

Driscoll walked briskly toward the cemetery and Miss Langley. Blue jays, sparrows, pigeons, white tailed doves, two mallard ducks, and four Canadian geese fluttered about the woman, screeching for crumbs.

"Saint Therese of the Birds," Driscoll exclaimed.

Silence was his reply and he realized he was intruding on a mysterious and private ceremony. He'd wait until her service was completed.

The crumb distribution ended, yet the birds lingered, insatiable and rude. The woman opened an instrument case and produced a silver flute, which she began to play. Pastoral and rustic was the melody. As if in a trance, the birds listened.

The melody stopped and the birds flew away, perching themselves on the branches of the surrounding elms and oaks.

"Bravo!" Driscoll cheered. "Those are some lucky birds. Not only lunch, but a concert."

The woman stared at him. "Quiet!" Kneeling, she whispered:

"Confiteor Deo omnipotenti, beatae Mariae, semper Virgini, beato Michaeli archangelo, beato Joanni Baptistae, sanctis apostolis Petro et Paulo, omnibus sanctis, et tibi, Pater, quia pecavi nimis cogitatione, verbo et opere, mea culpa, mea culpa, mea maxima culpa."

Then she rose and faced Driscoll. "These grounds are my confessional," she said. "Where do you go to ask for forgiveness?"

"The barroom at Sullivan's."

"Another soiled soul. Well, it wasn't my music, nor my transgressions, you came to hear. I saw you ringing my bell a moment ago."

"If I knew I'd hear a masterful flute solo, I'd have come here first."

"Thank you. I used to teach musicology at Juilliard, but then my son took ill and I had to change careers." The woman smiled. "And you are?"

"My name is Driscoll. Police Lieutenant John Driscoll."

"Wait a minute. You have that big-town aroma about you. Let me guess, Chicago...no, Philadelphia."

"New York."

The woman showed surprise. "A little out of your jurisdiction, aren't you?"

"I'm conducting an investigation into the death of a young girl as a result of an automobile accident."

"I'm at a loss," the woman said. "If she died as a result of a car accident, what's there to investigate?"

"Doctor Colm Pierce was at her bedside when she died."

Understanding registered. "Sweet Lord! What are you saying? Are you accusing Colm?"

"Not at all. I just have a few questions."

"It was at my knees he learned the catechism, Lieutenant. Colm was taught to confess his sins before he committed them. What is it you're after?"

"I understand you were Colm's nurse at Wellmore."

"My care for the boy was ages ago. What does that have to do with anything happening now?"

"We're doing a background search of all the physicians on call that afternoon. Routine investigation. Nothing to be alarmed about."

"But how did you find me?"

It was the question Driscoll had hoped she would not ask. "On my visit to Wellmore I met Gunther Etteridge, and he sent me to you."

"I see. How is dear Gunther?"

"He misses Colm."

The response brought a smile to Langley's lips. "Well, let's get on with the questioning."

"I want to know more about Doctor Pierce. How is it such an accomplished radiologist got his start in a psychiatric facility for children?"

"The dear boy's early years were an abomination. A regular horror show. And then there was the fire that burned down his family's home, and all that happened there. Colm O'Dwyer, that was Colm's true name. He became a ward of the state in some squalid institution until Wellmore took him in on a philanthropic scholarship funded by the Pierce estate. That's when Edgar Pierce entered the picture. He took a liking to the boy. In a strange way, the boy resembled Edgar and could have passed for his legitimate son. The jet-black hair, those aquamarine eyes, the cleft in his chin. You could say, as soon as Edgar saw him, he saw himself. And in some ways, emotionally, he had already adopted him."

A regular horror show, thought Driscoll. What was it Sheriff Karp had said? The occupants of the boy's house were into pain. Lots and lots of pain. That meant the boy was brought up in an abusive environment. So abusive that he torched his house and killed his family only to end up in squalor as a ward of the state. Any Behavioral Studies graduate from Quantico would tell an inquirer that he was witnessing the birth of a psychopath.

"Driscoll. That name has its roots in the Old Sod. Do you speak the language, Lieutenant?"

"Some."

"Colm loved the water. An loch ag crithlonraigh ina ciuineas glaoighean se ar go leor croi uaigneach, An loch ag crithlonraigh ina ciuineas glaoighean se ar go leor croi uaigneach," Langley recited. The lake shimmering in its stillness calls to many a lonely heart.

"That's beautiful. You write poetry?"

"Not I. But Colm the Bard did. At sixteen the boy won a national poetry contest."

"He wrote in Gaelic?"

"He was fluent. Still is."

From psychopath to serial killer, thought Driscoll. "Regarding Wellmore, how is it you fit in?" he asked.

"Edgar wanted it that way."

"Why you?"

"Edgar promoted me to Director of Children's Services, with a special responsibility to act as surrogate mother to Colm. We had something in common, Edgar and me. We both had lost a son. That's what brought us closer together. On a cruise to the Galapagos Islands, Edgar was restless, not his usual jovial self. I found out what was troubling him. He confessed that he had fallen in love with me. From there on, he was part of my life. He never wanted to discuss his home life, and that was fine with me. I was like a second wife to him, and he was a dream husband. It was an idyllic time, filled with wonder. And then Alzheimer's came between us. He would forget appointments. Miss meetings he had called for. And then one day he woke up and didn't know why he was in my bed. He got dressed and left. I never saw him again." She sighed. "But you're not here to do research for a romance novel, are you?"

"No."

"This is more than just idle curiosity, isn't it?"

"Miss Langley, like I said, I'm investigating this patient's death-"

"I realize that," she said with a smile. "But Colm's temper was never directed at children. He would never harm a child."

"Would he harm an adult?"

"You know Lieutenant, I think Alzheimer's might just be a little contagious." The woman had just slammed another door in Driscoll's face.

"As a nurse, Miss Langley, you may be doing an injured man a great deal of harm."

"The afternoon was lovely, Lieutenant. Thanks for the company." She then turned on Driscoll and walked away.

Driscoll stood alone in the cemetery, collecting his thoughts. From his conversation with Miss Langley he had discovered Pierce's mastery of the Gaelic tongue, and that he had a fascination for bodies of water. Was it not Gaelic that the derelict had heard? And was it coincidence that Monique, Deirdre, and Sarah's bodies were found near water? He had also learned that Pierce had been reared in an abusive home. So abusive that he had probably snapped and killed his family. And the man had a temper. That information came directly from his surrogate mother. Who better to know him? He thought of Margaret. A chill ran through his body. He unpocketed his cellular and called his office. Cedric Thomlinson answered the call.

"Where's Margaret?" Driscoll blurted.

"She's with Pierce. He invited her to his home."

Chapter 82.

The mansion stood at the apex of a circular driveway. Margaret had seen photographs of similar structures in the pages of Architectural Digest, Architectural Digest, but had never imagined she'd ever be inside one. but had never imagined she'd ever be inside one.

"A place like this usually charges admission," she said. "Does it come with a tour guide?"
