Here is exacty what Sokolov's Report says on the subject, of this "reliable source" Soloviev, who claimed Bux. stole money from the Imperial Family:
Sokolov:
Pg 126. In meeting with the prisoners in Tobolsk, he (Soloviev) he convinced them that he was preparing their salvation. Soloviev put their fears to rest and made them give up any personal initiative in that regard.
127. Deposition of Tatiana Botkina: Soloviev worked to their (the IF's) ruin. He occupied the important point in Tyumen, where he gave the directives to Petrograd and Moscow. He filtered all those who arrived. He stopped them all, and would not give the authorisation to go to Tobolsk except for one night only, and he would not give this permission except only those who were incapable of working in secret. In case of any disobedience to his orders he would deliver them up to the Soviet officers, with whom he was on the very best of terms...There was certainly never any organization and the supposed "300 officers" existed only in fiction.
pg 130: Deposition given to Serguiev by an officer in the Empress' personal regiment:" I spent all last winter (1917-18) in Tiumen, where I met Boris Nicholaievich Soloviev, who had married Rasputin's daughter. He told me he was the head of an organization dedicated to protect the Imperial family, in observing his situation, in the furnishing of everything needed to relieve their meals and comfort, and to take all measure to ward off dangerous people from them. According to Soloviev's promises, anyone sympathetic to his organisation would present themselves to him before undertaking anything to be done for the Imperial family. "In any case to the contrary" Soloviev said, "I will veto all such disposition and all such action." This "veto" would be accompanied by being turned over to the Soviet authorities. This was exactly what had happened to two Cavalry officers of the Guard and a woman. I don't know their names, but I can report to you that this fact was confirmed by Soloviev under oath."
Deposition of Constantine Semyonovich Melnik (husband of Tatiana Botkina): "During my stay in Tobolsk I became convinced that no such organization existed to rescue the Imperial Family; and I learned that the people who shared in their captivity, received only a small part of anything sent to them. By Soloviev's actions, I learned alot about N** who had been sent by an organization in Petrograd, but had been obliged to stay more than four months in Tyumen, where Soloviev also was. Only one time was N** permitted to go to Tobolsk for 24 hours only, at the moment the Emperor departed. I asked N** why he had obeyed Soloviev in this. N** told me that Soloviev had told him how he had delivered up two officers who had gone to Tobolsk without his permission, over to the local Tyumen Soviet. Well, those two had been sent by a Monarchist organization and so Soloviev could not just ignore them. Soloviev added that he would equally hand over to the Soviets anyone who disobeyed his orders."
pg 131: We see then, that according to the depositions of Markov and Sokolov (no relation to the author), that Soloviev throughout 1917-1918 had ties to Vyroubova. His sworn declarations, those of his wife, all confirmed by notations in their diaries, proved that he had known Rasputin for a very long time, but their relations became much more frequent after 1915.
When I deposed Soloviev myself, he tried to convince me that he had been a genuine monarchist, and that he married Rasputin's daughter for love.
Here are the facts: The inquest established that, according to numerous testimony, at the moment of the Revolution, Soloviev was an officer in the Second Infantry Regiment. He occupied an important post in the revolutionary government which had formed in the Duma after the Emperor's abdication. General Potapov (actually a Bolshevik general as we would see) was the most influential person, who admitted this himself, became his aide de camp.
...
I finish this chapter with the following fact: Some fifteen days before the Emperor was transferred to Tobolsk, Soloviev indicated precisely in his diary the exact date for the transfer, 12 April 1918 - the impending date of this was unknown to everyone else. Do we need further proof of the relationship which existed between Yakovlev and Soloviev?"
