Prokaryote delivery capsules

The Prokaryote delivery capsules are small, brittle brown containers engineered to disperse a microorganism through the air when crushed. Their design makes them more than a way to store a dangerous sample: the capsules’ physical properties explain how Simon Illyan was exposed, while the shortage discovered in the evidence store points to deliberate theft by Lucas Haroche.

Design and Operation

The capsules were kept in a shockproof gel-pack inside a bio-sealed box. Its lining had six parallel slots, and the inventory described six vector-delivery units. One had been removed for examination five years earlier and recorded as destroyed. When Miles Vorkosigan and Ivan Vorpatril inspected the box, however, only three capsules remained. The discrepancy meant that two more were unaccounted for.

The container itself offered little protection against someone with authorized access. Its numeric lock was simple, and the access code appeared in the inventory description. Forensics found that the lock had not been forced. Nor had the box’s screamer-signal circuit, which was intended to detect removal from the evidence store, ever been activated. The capsules could therefore disappear without a forced entry or an alarm, even while the box remained in its assigned place.

Vaughn Weddell’s analysis clarified what the capsules were for. They were neither permeable nor soluble, and were not designed to be swallowed. Instead, they had to be broken, a task that could be done by pinching one between the fingers. The released material formed a fine powder that dispersed in air. Its prokaryotes were enclosed in hollow, sporelike particles: too large to be loaded efficiently as bare organisms, but capable of floating until they reached a wet surface, such as a mucous membrane or the bronchia. There, the delivery particles dissolved and released their contents.

Discovery and Demonstration

The missing capsules were found during Miles’s inspection of the evidence store. The box contained three, rather than the five expected after the earlier examination sample had been removed. The count transformed the inventory discrepancy into a concrete lead: some of the units had been taken, although neither the unforced lock nor the inactive alarm showed how.

Miles assigned the remaining evidence to separate lines of inquiry. He ordered one capsule sent for molecular analysis so Weddell could determine whether its contents matched the material flushed from Simon Illyan’s chip. He placed the final two under his Auditor’s seal and directed that the box remain secured. When Miles later asked Simon Illyan whether he had swallowed a small brown capsule, Illyan said he had taken no medication in the past thirty years except what his personal physician administered directly. Weddell’s findings supplied an important correction to the question: swallowing was not the intended route of exposure.

To demonstrate the mechanism, Miles returned with witnesses to Aisle 5 of Weapons Room IV. He had Ivan hand down the familiar bio-sealed box from Shelf 9, checked that his Auditor’s seal remained unbroken, and took one of the two capsules still inside. He pressed it between his fingers. The capsule snapped, releasing a tan powder that briefly hung in the air before dispersing. Weddell advised allowing at least ten minutes for it to spread through the room. The demonstration made the proposed airborne delivery visible and repeatable rather than merely theoretical.

Theft and Use

Gregor’s questioning established that Haroche had taken the two missing capsules. Haroche said he conceived of using the Komarran powder after seeing Miles leave Simon Illyan’s office in distress. A few days later, while Simon Illyan regularly visited Haroche’s office to check facts and obtain his opinion, Haroche used one capsule to expose him. When nothing seemed to happen for about a week, Haroche dosed him again. He had not anticipated how slowly the symptoms would emerge or how severe they would become, but believed the attack would not kill Simon Illyan.

Haroche also explained why he had been able to remove the capsules. The security tag monitored the box, not its contents; he had walked into the evidence store while authorized to take material and had not been searched. The unforced lock and silent alarm were therefore not signs that the capsules had remained untouched. The security system could register a container’s removal while leaving its contents vulnerable to someone whose access looked legitimate.

Significance

The capsules connect three strands of the investigation: the unexplained damage to Simon Illyan’s memory chip, the evidence-store inventory, and the means by which Haroche carried out the sabotage. Their count provides evidence of removal; Weddell’s analysis identifies the delivery method; and Miles’s demonstration shows how a capsule releases its contents. Haroche’s admission then ties those physical clues to a deliberate act and its repeated administration.

Their importance depends on a contrast between concealment and exposure. In the evidence store, the capsules are small enough to be overlooked inside an apparently secure box, and the records describe them as inventory. Once one is crushed, however, its function becomes legible in the air: a hard-to-track container gives way to a dispersal mechanism. The capsules thus turn an obscure discrepancy in stored material into a demonstrable explanation of how Simon Illyan’s chip was sabotaged.
