Microphone recorder

The microminiaturized wire recorder is a miniature surveillance device used by Ben Caxton and Jill Boardman to listen in on the guarded hospital suite where Valentine Michael Smith is being held. Its concealed construction makes covert recording possible, while its repeated handling exposes the danger and practical ingenuity required to gather information around Smith. The object moves from Ben’s hand into Jill’s nursing work and back as a spool of recorded voices, turning a hidden machine into the material basis for an investigation.

Design and Listening Method

Ben presents the recorder as a small object about the size and shape of a cigarette lighter, then explains its usefulness as a spy’s instrument. Its wire is spring-driven, so a snooper circuit cannot detect the mechanism; its electronic components are packed into plastic, and Ben says it could survive a fall from a cab. The radioactive power source is shielded, and the wire records for twenty-four hours. A spool can then be removed and replaced with another, with the spring built into each spool and already wound.

The device’s pickup is separate from its recorder: Ben describes a listening attachment with two “donkey's ears.” Fastened flat against a wall with its concave side toward the surface, it picks up speech in the adjoining room. This arrangement lets Jill listen without entering Smith’s suite, but it also makes success dependent on finding a wall and neighboring room that can be approached without drawing attention. The recorder’s minute scale conceals the technology; its placement and upkeep, by contrast, require careful management of people, rooms, and routine.

Installation and Maintenance

Jill places the bug on the wall of a room adjoining Smith’s suite, using a closet shelf as cover. The patient there is confined to bed, and Jill has an ordinary reason to stop and gossip with her. While chatting about how the maids never dusted the high closet shelves, she sticks the device against the wall. The disguise works because the operation is folded into familiar nursing activity rather than staged as a conspicuous intrusion.

The next day, Jill removes the used spool and inserts a fresh one while the patient is asleep. When the woman wakes with Jill still standing on a chair, Jill redirects her with an invented ward rumor. The recorder thus depends not just on concealment but on Jill’s ability to improvise plausible conversation when its maintenance becomes visible. Sending the exposed wire to Ben by mail offers another practical choice: the hospital post office seems safer to Jill than a theatrical cloak-and-dagger delivery.

A third spool change fails. Jill waits until the patient is asleep, but the woman wakes just as Jill has climbed onto the chair and has her hand on the recorder. Their brief exchange leaves Jill unable to continue using that room without risking discovery. She decides to move the bug to an empty room that is part of Smith’s suite, but by the time she can return, the guard has been doubled: two marines are inside. She enters with a pass key she no longer needs, finds the door already unlocked, and leaves after directing the guards not to sit on the bed. The recorder has not been detected in the passage, but the reinforced security makes the original plan untenable.

Recordings and Consequences

When Jill meets Ben again, he warns her not to speak names or anything but trivialities because he may be wired. She hands him the whole recorder, not merely a spool. Ben does not comment on the change; he instead gives her a copy of the afternoon Post and points to a column in his own syndicated outlet. The recorder’s return is folded into the appearance of an ordinary visit, matching the everyday cover that had enabled Jill to install it.

Ben later gives Jill a typed transcript of what the first spool captured. He has labeled the speakers “First Voice,” “Second Voice,” and so on, adding names where he has subsequently been able to identify them. Across the top he notes that all the voices, identified or not, are masculine. Most of the transcript concerns Smith’s routine care: feeding, washing, massage, and twice-daily exercise supervised by Dr. Nelson and another doctor whom Jill takes to be Dr. Thaddeus. The recording therefore documents not only what is said but the tightly managed pattern of Smith’s treatment.

The transcript also contains a longer passage unrelated to the patient’s physical care, which Jill reads and rereads. The recorder’s importance consequently exceeds its technical achievement: a device planted to listen through a wall yields a record that can be examined, attributed, and interpreted after the listening itself is over. Its operation links covert access in the hospital to the emerging investigation of what is happening to Smith, while the transcript’s unexplained passage leaves the device’s most consequential discovery poised for further revelation.
