delivered the opinion of the Court.
In this case we are called upon to apply that venerable principle of Maryland criminal law which prohibits the use of a defendant’s significantly incriminating remark when that statement was extracted from him by promise of favor or threat of punishment.
*157 The facts are not in dispute. At 2:30 a.m. on November 14, 1974, two narcotics officers of the Baltimore City Police Department, armed with a warrant, arrived to conduct a search for controlled dangerous substances at the house where petitioner Bernard Lee Stokes and his wife were living with several other persons. Upon entering the dwelling, the officers immediately went up to the Stokes’ third floor bedroom where the two were sleeping. After identifying themselves, explaining their purpose, and advising the couple of their Miranda rights, the officers proceeded to search the room. Following an unsuccessful exploration lasting about five minutes, the officers terminated their quest, turned to Stokes and informed him "that if he would produce the narcotics, his wife would not be arrested.” As a result of this assurance, the petitioner revealed to the officers that drugs were hidden in a "drop ceiling” on the left side of the room. 1 The officers then seized the contraband, heroin, and charged Stokes with its possession. At the ensuing trial in the Criminal Court of Baltimore (Grady, J.), Stokes objected to and moved to suppress both the heroin and his statement as to its location. The motion was denied, and Stokes was convicted of the possession charge.
On certiorari to this Court, after his conviction was affirmed in an unreported opinion by the Court of Special Appeals, petitioner contends, as he unsuccessfully contended both in the trial court and in the intermediate appellate court, that his inculpatory statement was involuntary since it was induced by a police promise not to arrest his wife. The State counters with an assertion that this promise, being one primarily designed "to benefit a relative” of the accused, does not impair the admissibility of the inculpatory statement extracted from Stokes nor the drugs which it revealed. Alternatively, the State urges that even *158 if the petitioner’s statement is determined to have been involuntarily made, the seized heroin was properly admitted into evidence because the secreted drugs would inevitably have been discovered by the searching police without reliance on Stokes’ guidance. Since we do not agree with either of these assertions, we will reverse the judgment entered in this cause.
Little more than one year has elapsed since this Court, in
Hillard v. State,
[ujnder Maryland criminal law, independent of any federal constitutional requirement, if an accused is told, or it is implied, that making an inculpatory statement will be to his advantage, in that he will be given help or some special consideration, and he makes remarks in reliance on that inducement, his declaration will be considered to have been involuntarily made and therefore inadmissible.
[Thus,] it must be shown [by the State] ... that the defendant’s decision to make a statement ... was not induced by any promise of favor or threat of punishment. [286 Md. at 153-154 ,406 A.2d at 420 .]
Recognizing the substantial barrier to its position caused by
Hillard,
the State, in its effort to parry defeat, urges that the teachings of two of our earlier cases,
Rogers v. State,
In
Rogers,
at the time the defendant and his sister were being questioned in the same room about a homicide, the brother confessed to having committed the murder following a police remark that "if your sister is innocent you are the only one who knows so, and it is your duty as a man to tell what you know about it.”
In
Jones,
the trial court was faced with a claim, contradicted by the police, that the officers threatened prosecution of the defendant’s pregnant common law wife in order to induce him to confess to a murder.
Turning now to the facts before us in this case, it is clear that the police not only promised petitioner they would not arrest his wife if he revealed the location of the heroin, but, *160 in addition, this promise bore fruit, for it is equally apparent that Stokes’ statement directly resulted from that entreaty. The State’s case is therefore reduced to dependence on an argument that "a promise to benefit a relative is not that type of advantage, help or special consideration to an accused which is contemplated by Hillard. ” Responding to this contention with respect to the reach of Hillard, we make clear here, even if beclouded until now, that the mandate of that case encompasses the issue presented in this case and is dispositive of it. The rule in Hillard announces that a statement is rendered involuntary if it is induced by any official promise which redounds to the benefit or desire of the defendant. And this necessarily includes a promise not to harm (physically or emotionally) a near relative with whom the defendant naturally has a close bond of affection. 2 Indeed, in line with what we have just said with respect to a near relative, our predecessors in Jones v. State, supra, by their very willingness to examine the issue whether sufficient evidence existed to support the finding of the trial court that no threat to arrest the defendant’s common law wife was in fact made, necessarily recognized that such an inducement, if proven, would have rendered the defendant’s statement involuntary.
That principle of Maryland criminal law which excludes an inculpatory statement induced by "any promise of favor or threat of punishment,”
Hillard, supra
at 154,
Even if the defendant believed that his common law wife would not be held if he confessed, the confession was not thereby rendered involuntary or inadmissible merely because it was made to release another from suspicion of guilt: there must also be *162 sufficient evidence that the confession was actually induced by a threat or promise or other [improper] cause. [229 Md. at 172 ,182 A.2d at 788 (emphasis added):]
This view, stated in
Jones,
is also in line with those espoused by a number of our sister states that "where no express or implied promise or threat is made by the police, a suspect’s belief that his cooperation will benefit a relative will not invalidate the . . . [statement].”
People v. Steger,
Accordingly, petitioner’s statement revealing the location of the illegal drugs for which he was convicted of possessing was involuntary since it was induced by an improper official promise not to arrest his wife, and is therefore inadmissible. Hillard v. State, supra.
The State, anticipating our conclusion that petitioner’s statement was involuntary, argues alternatively that the drugs recovered from Stokes were obtained "by means sufficiently distinguishable [from the exploitation of the illegality] to be purged of the primary taint,”
Wong Sun v. United States,
[T]he prosecution must establish, first, that certain proper and predictable investigatory procedures would have been utilized in the case at bar, and second, that those procedures would have inevitably resulted in the discovery of the evidence in question. [LaCount and Girese, supra at 491.]
For authorities supporting the text of this summary see
United States v. Brookins,
The significance of the word "would” cannot be overemphasized. It is not enough to show that the evidence "might” or "could” have been otherwise obtained. Once the illegal act is shown to have been in fact the sole effective cause of the discovery of certain evidence, such evidence is inadmissible unless the prosecution severs the causal connection by an affirmative showing that it would have acquired the evidence in any event. In order to avoid the exclusionary rule, the government must establish that it has not benefitted by the illegal acts of its agents; a showing that it might not have so benefitted is insufficient. [Maguire, supra at 315.]
As may be seen from the exhaustive chronicling of the multifold authorities throughout the nation by the Iowa Supreme Court in
State v. Williams,
Consequently, the judgment of the Court of Special Appeals affirming the conviction and sentence must be reversed. In reversing on an evidentiary point, we would ordinarily direct remanding of the cause to the trial court for a new trial, but since it appears to us evident (and the State does not suggest otherwise) that there can be no valid conviction here without the illegally obtained statement and heroin, we this time will reverse without authorizing a new trial.
Judgment of the Court of Special Appeals reversed, and cause remanded to that court with instructions that it reverse the judgment of the Criminal Court of Baltimore, without a new trial.

Notes
. At trial, the Assistant State’s Attorney, when reciting the agreed upon facts, additionally noted at one point that the petitioner "went to a location, a drop ceiling,” and produced packets of drugs. Whether the drugs were uncovered as a result of petitioner’s words or by his deeds is irrevelant, for it is settled that an act can constitute a statement for evidentiary purposes. See McCormick’s Handbook on Evidence § 250 (2d. Ed. by E. Cleary 1972).
. While we now hold that a promise not to arrest a defendant’s near relative benefits him sufficiently to render his statement induced by that promise involuntary, we have no occasion here to consider whether kinship is required, or the degree of closeness (kinship or otherwise) that a defendant must have to the affected third party, before the coercive effect of such inducements may be found to exist.
