"Either he or another spy sabotaged this and all the other counters I've looked at. It would have taken a skilled man no more than an hour. In the case of this instrument." The engineer turned the fixed detector over. "You see that the electrical parts have been disconnected, except for the test circuit, which was rewired. Borodin and I removed this from the forward bulkhead. This is skilled work; whoever did this is no amateur. I believe that an imperialist agent has sabotaged our ship. First he disabled our radiation monitor instruments, then he probably arranged a low-level leak in our hot piping. It would appear, comrades, that Comrade Petrov was correct. We may have a leak. My apologies, Doctor."

Petrov nodded jerkily. Compliments like this he could easily forego.

"Total exposure, Comrade Petrov?" Ramius asked.

"The greatest is for the enginemen, of course. The maximum is fifty rads for Comrades Melekhin and Svyadov. The other engine crewmen run from twenty to forty-five rads, and the cumulative exposure drops rapidly as one moves forward. The torpedomen have only five rads or so, mostly less. The officers exclusive of engineers run from ten to twenty-five." Petrov paused, telling himself to be more positive. "Comrades, these are not lethal doses. In fact, one can tolerate a dose of up to a hundred rads without any near-term physiological effects, and one can survive several hundred. We do face a serious problem here, but it is not yet a life-threatening emergency."

"Melekhin?" the captain asked.

"It is my engine plant, and my responsibility. We do not yet know that we have a leak. The badges could still be defective or sabotaged. This could all be a vicious psychological trick played on us by the main enemy to damage our morale. Borodin will assist me. We will personally repair these and conduct a thorough inspection of all reactor systems. I am too old to have children. For the moment, I suggest that we deactivate the reactor and proceed on battery. The inspection will take us four hours at most. I also recommend that we reduce reactor watches to two hours. Agreed, Captain?"

"Certainly, Comrade. I know that there is nothing you cannot repair."

"Excuse me, Comrade Captain," Ivanov spoke up. "Should we report this to fleet headquarters?"

"Our orders are not to break radio silence," Ramius said.

"If the imperialists were able to sabotage our instruments . . . What if they knew our orders beforehand and are attempting to make us use the radio so they can locate us?" Borodin asked.

"A possibility," Ramius replied. "First we will determine if we have a problem, then its severity. Comrades, we have a fine crew and the best officers in the fleet. We will see to our own problems, conquer them, and continue our mission. We all have a date in Cuba that I intend to meet—to hell with imperialist plots!"

"Well said," Melekhin concurred.
