did it come from?" asked the druggist, unable longer to restrain his curiosity.
"I got it up at Pearcy's," Kennedy replied frankly, turning to observe whether the druggist might betray any knowledge of it.
"That's strange," he replied in genuine surprise. "Our water in Stratfield is supplied by a company to a large area, and it has always seemed to me to be of great organic purity."
"But the pipes are of lead, are they not?" asked Kennedy.
"Y-yes," answered the druggist, "I think in most places the service pipes are of lead. But," he added earnestly as he saw the implication of his admission, "water has never to my knowledge been found to attack the pipes so as to affect its quality injuriously."
He turned his own faucet and drew a glassful. "It is normally quite clear," he added, holding the glass up.
It was in fact perfectly clear, and when he passed some of the gas through it nothing happened at all.
Just then a man lounged into the store.
"Hello, Doctor," greeted the druggist. "Here are a couple of fellows that have been investigating the water up at Pearcy's. They've found lead in it. That ought to interest you. This is Dr. Gunther," he introduced, turning to us.
It was an unexpected encounter, one I imagine that Kennedy might have preferred to take place under other circumstances. But he was equal to the occasion.
"We've been sent up here to look into the case for the New York Star," Kennedy said quickly. "I intended to come around to see you, but you have saved me the trouble."
Dr. Gunther looked from one of us to the other. "Seems to me the New York papers ought to have enough to do without sending men all over the country making news," he grunted.
"Well," drawled Kennedy quietly, "there seems to be a most remarkable situation up there at Pearcy's and Minturn's, too. As nearly as I can make out several people there are suffering from unmistakable signs of lead poisoning. There are the pains in the stomach, the colic, and then on the gums is that characteristic line of plumbic sulphide, the distinctive mark produced by lead. There is the wrist-drop, the eyesight affected, the partial paralysis, the hallucinations and a condition in old Pearcy's case almost bordering on insanity--to enumerate the symptoms that seem to be present in varying degrees in various persons in the two houses."
Gunther looked at Kennedy, as if in doubt just how to take him.
"That's what the coroner says, too--lead poisoning," put in the druggist, himself as keen as anyone else for a piece of local news, and evidently not averse to stimulating talk from Dr. Gunther, who had been Pearcy's physician.
"That all seems to be true enough," replied Gunther at length guardedly. "I recognized that some time ago."
"Why do you think it affects each so differently?" asked the druggist.
Dr. Gunther settled himself easily back in a chair to speak as one having authority. "Well," he began slowly, "Miss Pearcy, of course, hasn't been living there much until lately. As for the others, perhaps this gentleman here from the Star knows that lead, once absorbed, may remain latent in the system and then make itself felt. It is like arsenic, an accumulative poison, slowly collecting in the body until the limit is reached, or until the body, becoming weakened from some other cause, gives way to it."
He shifted his position slowly, and went on, as if defending the course of action he had taken in the case.
"Then, too, you know, there is an individual as well as family and sex susceptibility to lead. Women are especially liable to lead poisoning, but then perhaps in this case Mrs. Pearcy comes of a family that is very resistant. There are many factors. Personally, I don't think Pearcy himself was resistant. Perhaps Minturn was not, either. At any rate, after Pearcy's death, it was I who advised Minturn to take the electrolysis cure in New York. I took him down there," added Gunther. "Confound it, I wish I had stayed with him. But I always found Josephson perfectly reliable in hydrotherapy with other patients I sent to him, and I understood that he had been very successful with cases sent to him by many physicians in the city." He paused and I waited anxiously to see whether Kennedy would make some reference to the discovery of the strychnine salts.
"Have you any idea how the lead poisoning could have been caused?" asked Kennedy instead.
Dr. Gunther shook his head. "It is a puzzle to me," he answered. "I am sure of only one thing. It could not be from working in lead, for it is needless to say that none of them worked."
"Food?" Craig suggested.
The doctor considered. "I had thought of that. I know that many cases of lead poisoning have been traced to the presence of the stuff in ordinary foods, drugs and drinks. I have examined the foods, especially the bread. They don't use canned goods. I even went so far as to examine the kitchen ware to see if there could be anything wrong with the glazing. They don't drink wines and beers, into which now and then the stuff seems to get."
"You seem to have a good grasp of the subject," flattered Kennedy, as we rose to go. "I can hardly blame you for neglecting the water, since everyone here seems to be so sure of the purity of the supply."
Gunther said nothing. I was not surprised, for, at the very least, no one likes to have an outsider come in and put his finger directly on the raw spot. What more there might be to it, I could only conjecture.
We left the druggist's and Kennedy, glancing at his watch, remarked: "If you will go down to the station, Walter, and get that package we left there, I shall be much obliged to you. I want to make just one more stop, at the office of the water company, and I think I shall just about have time for it. There's a pretty good restaurant across the street. Meet me there, and by that time I shall know whether to carry out a little plan I have outlined or not."
Chapter XXX
The Electrolytic Murder
We dined leisurely, which seemed strange to me, for it was not Kennedy's custom to let moments fly uselessly when he was on a case. However, I soon found out why it was. He was waiting for darkness.
As soon as the lights began to glow in the little stores on the main street, we sallied forth, taking the direction of the Pearcy and Minturn houses.
On the way he dropped into the hardware store and purchased a light spade and one of the small pocket electric flashlights, about which he wrapped a piece of cardboard in such a way as to make a most effective dark lantern.
We trudged along in silence, occasionally changing from carrying the heavy package to the light spade.
Both the Pearcy and Minturn houses were in nearly total darkness when we arrived. They set well back from the road and were plentifully shielded by shrubbery. Then, too, at night it was not a much frequented neighborhood. We could easily hear the footsteps of anyone approaching on the walk, and an occasional automobile gliding past did not worry us in the least.
"I have calculated carefully from an examination of the water company's map," said Craig, "just where the water pipe of the two houses branches off from the main in the road."
After a measurement or two from some landmark, we set to work a few feet inside, under cover of the bushes and the shadows, like two grave diggers.
Kennedy had been wielding the spade vigorously for a few minutes when it touched something metallic. There, just beneath the frost line, we came upon the service pipe.
He widened the hole, and carefully scraped off the damp earth that adhered to the pipe. Next he found a valve where he shut off the water and cut out a small piece of the pipe.
"I hope they don't suspect anything like this in the houses with their water cut off," he remarked as he carefully split the piece open lengthwise and examined it under the light.
On the interior of the pipe could be seen patchy lumps of white which projected about an eighth
