His eyes narrowed, though she saw the ghost of a smile on his lips. “All right. What is it that you want to do about this formula?”
CHAPTER 16
The dark house across the street was large and well-appointed, sitting comfortably in the center of a rectangular property at a respectable address. In the wee hours of a windswept Wednesday morning, curtains were drawn across dark windows up and down the street. Saffron and Alexander leaned casually on a stone wall, their eyes on the gate.
Glancing to the left and right, Alexander muttered, “Are you sure you want to do this? This is completely different from the university. We have absolutely no business showing up here at this time of night.”
The honest answer was no, Saffron wasn’t sure. But she couldn’t think of another way to determine if the formula was a fluke. Saffron took a deep breath, her face set. “Yes. Now, you go over first and unlatch the gate. Then, we search. Do you remember what aconite looks like?”
He nodded, slipped his jacket from his shoulders, then jogged across the street. When she gave him a quick wave, indicating that no one was coming, Alexander set his jacket onto the top of the wall, grabbed the top of the tall stony ledge and pulled himself up. He disappeared onto the other side. Saffron was impressed by his physical acumen, but quickly reprimanded herself for being distracted. She looked up and down the street, shivering slightly in the wind.
Saffron rushed across the street toward the gate when it opened. It was nearly pitch black in the garden. The moon had not yet risen, and the high stone wall and voluminous foliage blocked most of the orange glow of the streetlights. They crept nearer to the house to ensure it was silent and still. Then, as agreed, Alexander remained in the front to keep watch while she circled the house in search of the conservatory.
It was well known that Dr. Berking had amassed a personal collection of plants that rivaled that of the university, but his collection was restricted to plants of Southeast Asia, where Dr. Berking focused his studies. Another reason Berking’s interest in the expedition was suspicious, since he had never worked on plants from South America.
Aconite was not a plant native to that region, but Saffron couldn’t imagine that, if Berking required plant for a nefarious purpose, he wouldn’t grow it himself. A botanist was still a botanist, even if they did want to poison someone with the fruits of their labors. It was likely he’d cultivated it in a place he could tend it and harvest it without notice rather than at the university. Camouflaged among his other plants seemed the most logical place.
Before approaching the fogged windows of the glassed conservatory, she took a quick look around the garden and the barely visible houses beyond. A sweeping breeze rushed through, making all the trees and bushes shake and sway. It was as if the world was undulating around her. Closing her eyes to the vision of blackness, she visualized aconite’s hooded blooms and deeply lobed leaves. It should be easy enough to identify if Berking had it inside.
Saffron crept toward the clouded glass door, wondering where Berking’s servants were, for a grand house like this certainly warranted multiple servants. Not even the lights from the kitchen were on. Perhaps it was their night off, if Berking was also absent as the calendar on Pierce’s desk had indicated he would be.
Holding her breath, Saffron tested the wrought iron door handle to the conservatory. It squeaked slightly, but gave. She carefully stepped inside the warmth of the greenhouse.
A faint glow from an interior lamp provided meager light, and Saffron didn’t need more to know that Berking was right to be proud of his conservatory collection. The large room was crowded with verdure. Heady floral scents made her lightheaded, both with the smell and excitement. She could detect the scent of a blooming member of the Hedychium genus nearby, and followed her nose to an enormous potted plant emanating a heavenly smell like honeysuckle.
She glanced about the dark room. She couldn’t very well follow her nose to aconite. Saffron determined the most likely location for Berking to grow it would be under cover of a larger plant, as aconite would grow without full light, and that would reduce the chance of any fellow botany enthusiasts seeing it and asking questions. Outdoors, it ran the risk of being noticed by a gardener who might spill Berking’s secret.
She considered how easy it would be for Berking to have poisoned Mrs. Henry with several of the plants in the room. But surely, if Berking were a suspect, the police would have searched his home and logged all the poisonous plants he had, like she had done for the university. Did the police force have a botanical expert to do such things?
